Are there more than 500 solar systems in the universe?
The universe consists of more than 500 solar systems as of now or as of our limited knowledge on the universe.
Our solar system is present inside the Milky Way galaxy.
The Milky Way galaxy is called so because the Romans named it as they found the earth's skyline at night to resemble that of a band and a patch of milk..
Can we see solar system formation happening today?
We can't see the formation of our own Solar System, but we can see it happening everywhere we look, so we assume our Solar System formed in the same way.
Here's an article from Universe Today about planetary formation, and another about how the gas giants might have formed quickly..
How can astronomers determine how our solar system formed?
Astronomers feel confident that our Solar System formed by accretion because now they are able to glimpse a similar process occurring in part of the Orion Nebula.
This planet-forming area is on the near side of a giant cloud complex that embraces much of the constellation Orion, 1,500 light- years from Earth..
How did astronomers believe that our solar system was formed?
The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula.
A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula.
The Sun formed in the center, and the planets formed in a thin disk orbiting around it..
How did scientists discover how the solar system formed?
French astronomer and mathematician Pierre-Simon Laplace first suggested in 1796 that the Sun and the planets formed in a rotating nebula which cooled and collapsed.
The theory argued that this nebula condensed into rings, which eventually formed the planets and a central mass - the Sun..
How do astronomers know that the age of the solar system is about 4.5 billion years old?
The age of the solar system, derived from the study of meteorites (thought to be the oldest accessible material around) is near 5 billion years; that of the Earth is taken as 4.6 billion years.
The oldest rocks on Earth are dated as 3.8 billion years..
How do astronomers think our solar system formed?
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust.
The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova.
When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material..
How far away is another solar system?
For example, the nearest star system to ours is the triple star system of Alpha Centauri, at about 4.3 light years away.
That's a more manageable number than 25 trillion miles, 40 trillion kilometers or 272,000 AU..
How far is our solar system from the center of the universe?
The solar system sits some 26,500 light years from the galactic centre, about halfway along a spiral arm.
We orbit the centre of the Milky Way about once every 240 million years.
However, the universe has been expanding ever since the big bang, about 13.8 billion years ago..
How is a solar system formed?
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust.
The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova.
When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material..
How long ago do astronomers believe our solar system formed?
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust.
The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova.
When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material..
How long do scientists think the solar system formed?
Over time, materials within the protoplanets differentiated (reorganized) into different layers, which we can observe in planets today.
Scientists believe that the formation of the Sun lasted approximately 1 million years, and the formation of the planets was completed in approximately 100 million years..
How long does it take for a solar system to form?
Our solar system began as a collapsing cloud of gas and dust over 4.6 billion years ago.
Over the next 600 million years, called by geologists the Hadean Era, the sun and the planets were formed, and Earth's oceans were probably created by cometary impacts..
How long does it take for a star & planet system to form?
The process of planet formation around a star can take anywhere from several million to several billion years..
How long does it take to form a new planet?
In the warmer parts of the disk, closer to the star, rocky planets begin to form.
After the icy giants form there's not a lot of gas left for the terrestrial planets to accrete.
Planets that are rocky like Mercury, Venus, Earth and Mars may take tens of millions of years to form after the birth of the star..
How many how many solar systems are there?
How many solar systems are there? The latest data collected by NASA indicates that there are 3,916 solar systems within our Milky Way.
This means there are 3,916 stars with planets orbiting them in our single galaxy..
How many solar systems are there NASA?
The Short Answer:
Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy.
Our solar system is just one specific planetary system—a star with planets orbiting around it..
How old is the formation of the solar system?
Formation.
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust.
The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova.

The main idea of the solar system was proposed by the Polish astronomer Nicolaus Copernicus (1473-1543) who said that "the Sun is the center of the Universe" and made the planets move around it in perfect circles (in his book entitled, "On the Revolution of the Celestial Spheres", written in Latin and published in 1543 .
Solar system planets
Our solar system began to form around 5 billion years ago, roughly 8.7 billion years after the Big Bang.
A solar system consists of a collection of objects orbiting one or more central stars.
All solar systems start out the same way.
They begin in a cloud of gas and dust called a nebula ..
Solar system planets
Our solar system formed at the same time as our Sun as described in the nebular hypothesis.
The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planets [12]..

What is 98% of the solar nebula?
The gas was mostly hydrogen and helium that made up 98% of the mass of the initial solar nebula.
The remaining 2% of material in the nebula consisted of various ices and rock composed of the heavier elements.
The ices can be divided into three groups[1]..
What is the most commonly accepted theory of solar system formation?
Contemporary view.
The most widely accepted model of planetary formation is known as the nebular hypothesis.
This model posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years..
What is the theory of solar system formation?
The nebular theory states that our solar system formed from the gravitational collapse of a giant interstellar gas cloud—the solar nebula. – (Nebula is the Latin word for cloud.) Kant and Laplace proposed the nebular hypothesis over two centuries ago.
A large amount of evidence now supports this idea..

All solar systems start out the same way..
Where do astronomers believe that our solar system came from?
Regularities among the planets have led astronomers to hypothesize that the Sun and the planets formed together in a giant, spinning cloud of gas and dust called the solar nebula.
Astronomical observations show tantalizingly similar circumstellar disks around other stars..

Which astronomer built the solar system model?
The Copernican Model: A Sun-Centered Solar System.
The Earth-centered Universe of Aristotle and Ptolemy held sway on Western thinking for almost 2000 years.
Then, in the 16th century a "new" (but remember Aristarchus) idea was proposed by the Polish astronomer Nicolai Copernicus (1473-1543)..
Who discovered the formation of the solar system?
Copernicus' key discovery
It is hard to see how astronomers could have formed their current picture of how our Solar System came to be if we still thought everything orbited the Earth.
Copernicus's breakthrough is rightly lauded as one of the greatest scientific revolutions in history..
Why is it important to study the formation of the solar system?
Understanding the planets and small bodies that inhabit our solar system help scientists answer questions about its formation, how it reached its current diverse state, how life evolved on Earth and possibly elsewhere in the solar system, and what characteristics of the solar system lead to the origins of life..
- Astronomers feel confident that our Solar System formed by accretion because now they are able to glimpse a similar process occurring in part of the Orion Nebula.
This planet-forming area is on the near side of a giant cloud complex that embraces much of the constellation Orion, 1,500 light- years from Earth. - Astronomers have re-calculated the age of our solar system, and found it is very slightly older than we thought – 1.1 million years older, in fact.
That puts our solar system's age at 4.5684 billion years, rather than 4.5673 billion years. - Copernicus is often described as a lone astronomer who defiantly argued that the sun, not the Earth was at the center of the cosmos.
Copernicus' contributions to astronomy are so significant that they warrant their own term: The Copernican Revolution. - Different kinds of planets have different formation histories, with rocky planets assembling slowly and gas giants collapsing out of the disk very quickly.
But either way, computer simulations and studies of the Earth's mantle suggests that planet formation can take upwards of 10 million years. - In 1992, the first evidence of a planetary system other than our own was discovered, orbiting the pulsar PSR B1257+12.
Three years later, 51 Pegasi b, the first extrasolar planet around a Sunlike star, was discovered. - It is located in an outer spiral arm of the Milky Way galaxy called the Orion Arm, or Orion Spur.
Our solar system orbits the center of the galaxy at about 515,000 mph (828,000 kph).
It takes about 230 million years to complete one orbit around the galactic center. - The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planets [12].
- The Sun (and, of course, the rest of our solar system) is located near the Orion arm, between two major arms (Perseus and Sagittarius).
The diameter of the Milky Way is about 100,000 light-years and the Sun is located about 28,000 light-years from the Galactic Center. - The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula.
A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula.
The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
