Question: Question about the Galaxy, solar system, milky way?
This may seem like an obvious Question but:
The earth is a planet, which orbits the sun. The sun is a star. The other planets that orbit the sun (Mercury, Venus, etc) form our solar system. But now I get confused.
Out solar system is a what? is it a milky way? or a Galaxy? I know that rhe universe is EVERYTHING... But what comes before that? please help!!!!!!!
The earth is a planet that is in a solar system that is in a (????) that is in a (????) that is in a (????) PLEASE HELP
Our sun (one star) and the system of planets that surround it form our solar system. Our galaxy contains billions of stars, therefore billions of solar systems. The 'milky way' is just a nickname for our galaxy.
The Moon is a satellite of our planet Earth. The Earth is a satellite of our star, the Sun, along with the other seven planets, Pluto, the Asteroids, and our comets. The Sun is one of about 100 billion stars in our galaxy, called the Milky Way, which itself is rotating about its center (thought to be a black hole). The Milky Way is one of the estimated 100 billion galaxies in the Universe.
Our galaxy was named "The Milky Way" because of the way it appears to us on Earth, as a band of white across the black sky at night. What you see is a view of our galaxy from inside it. The actual shape is a disk with spiral arms, and our Sun is about 2/3 out from the center, in one of those arms.
The closest star to our Sun is just over 4.3 light-years away (Proxima Centauri), and that means it takes light 4.3 years to reach us from that star (the same goes for radio signals). The farthest galaxy we can possibly detect would be over 10 billion light-years away, because the estimated age of the Universe is 13.7 billion years (the time since the Big Bang, assuming that theory is correct).
A solar system is a collection of planets orbiting a star. OUR solar system is in a GALAXY called the MILKY WAY. The universe is made up of x amounts of galaxies.
The known universe consists of billions of galaxies - each one many several light years apart form the next. Our galaxy in which our solar system is situated is known as the Milky Way - as it looks like a splash of spilt milk across the sky. Each galaxy consists of several billion stars. Our nearest galaxy is the the Andromeda system .
