A planetary scientist is someone who studies solar systems (either our own or others) and also anything found in a solar system, e.g., planets, moons, asteroids, meteorites, comets, dust.
Planetary scientists are generally hybrid experts in astronomy, geology, chemistry, physics, and/or biology..
What are the big questions in astronomy?
Most astronomers work in offices and occasionally visit observatories, buildings that house ground-based telescopes used to observe natural phenomenon and gather data.
Some astronomers work full time in observatories..
What are the big questions in astronomy?
The zodiac is an imaginary "belt" or "roadway" which circles the heavens.
The Sun, Moon, and all the planets always stay within this belt.
Physically, this is just a consequence of the fact that all the major bodies in the solar system orbit the Sun in more-or-less the same plane..

Astronomers study vibrations on the surfaces of stars caused by waves that travel through their interiors.
Young stars have different vibrational patterns than old stars.
By using this method, astronomers have estimated the Sun to be 4.58 billion years old..
What questions does astronomy answer?
Astronomers study the origin and structure of the universe, including its planets, stars, galaxies and black holes..
What questions does astronomy answer?
They use ground-based equipment, such as radio and optical telescopes, and space-based equipment, such as the Hubble Space Telescope.
Some astronomers study distant stars, galaxies, and phenomena such as neutron stars and black holes, and others monitor space debris that could interfere with satellite operations..
