that remains to be seen. although the chances are slim, there might be an earth-like planet millions of light-years away!
All planets have gravity, not just Earth.
So far, we have not discovered any planets that resemble Earth.
They are different because terrestrial planets is any of Earth like planets including: Mercury, Venus, Mars, and Earth. However jovian planets are the Jupiter like planets including: Jupiter, Saturn, Uranus, and Neptune
In theory there are thousands, but because of limitations to our current technology we haven't found any.
No. The atmosphere just gets thicker and thicker until it crushes any space craft that we might send into it. There is no well defined solid surface like we have on earth and other rocky planets.
the stars emitt its own light. But the planets do not have any own light. It absorbs the light from the stars like a sun. It just reflects the light. And also the stars are far away from the earth than the planets. So we can found the twinkling of stars but not the planets.
No. Dwarf planets, or terrestrial planets like Earth or Mars, are too small to have ring systems.
It is the biggest the rock-like planets but is smaller than any of the gas planets. This makes it the fifth largest planet in the solar system
yes there are seasons like earth on other planets. Except, they all dont have the same tempuratures or the same period one or more season lasts.
Maybe, although we haven't found any planets with life-supporting conditions on them yet.
Yes, it depends on the resources they have. Like, Earth will die out if the sun dies out.
All plantes have rocks, the terrestrial planets like earth are almost entirely composed of rock. Jovian planets like Saturn have a solid core at the center of the planet composed of rock and ice.
