Yes! a number of stars in our galaxy are now believed to have their own planetary systems. We have till date found large gaseous planets very similar to our Jupiter. However recent findings also include rocky planets like mars and earth.
Yes there are.
They are in all three. Planets are in solar systems. There are lots of solar systems in a galaxy. There are lots of galaxies in the universe. So any planet is in a solar system, a galaxy and the universe.
other planets, other stars, other solar systems, other galaxy's, the rest of the universe, possibly more universes
Yes.The Milky Way is the edge of the galaxy in which we all live. Hence, this solar system resides in the Milky Way galaxy. Additionally, other stars in this galaxy have planets, and thus are their own solar systems.
A galaxy is made up of all sorts of matter, including stars. Many stars have object orbiting them, such as planets, asteroids, and even other stars. Solar systems orbit the galactic centre of a galaxy. (Solar systems don't orbit a galaxy, they ARE the galaxy)
We do not know. Although we have detected planets in other solar systems, we do not know what colors they are.
Planets outside our solar system are called exoplanets. Thousands of exoplanets have been discovered orbiting other stars in the Milky Way galaxy. They come in a variety of sizes and compositions, and many are quite different from the planets in our own solar system.
We don't know for sure - Andromeda is just too far to see that small detail. However, from current understanding of solar system formation, there will be billions of solar systems, planets and probably life .
Yes. As of December 12, 2013 nearly 800 systems have been discovered with planets, including more than 170 with multiple planets.
A solar system consists of one or two stars and one or more planets. A galaxy consists of numerous stars/solar systems.
There are eight planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The Milky Way is our galaxy, which contains billions of stars with their own solar systems.
not at all. solar systems consists of planets orbiting a star, and a galaxy consists of hundreds or even thousands of solar systems and either some or all galaxies have black holes in the center.
No. Earth is the 5th largest of the eight planets in the solar system. There are many more planets in the galaxy in other solar systems with numbers estimated in the hundreds of billions. Many that we know of are larger than Earth while some are smaller.
