There have been a number of extrasolar planets discovered that might resemble Earth. However, due to the extreme recency of the technology, and even the idea that Earth might not be unique, there is very limited data from the search for habitable planets.
On a more theoretical note, if you take into account the trillions of known and estimated galaxies, and the trillions of stars in most galaxies, and the number of those stars that have planetary systems orbiting them, and the number of those planetary systems orbiting in the habitable zone, the number of possible Earth-like planets is really astonishing.
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
planets are some thing like earth but there are alot of things that are not the same.Like there is no planet that can hold or keep things alive like earth can.amost all the planets have no gravitey like earth does .
In theory there are thousands, but because of limitations to our current technology we haven't found any.
Of all the planets the surface of Mars is closest to being like Earth.
No. Dwarf planets, or terrestrial planets like Earth or Mars, are too small to have ring systems.
Terrestrial type planets
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.
that remains to be seen. although the chances are slim, there might be an earth-like planet millions of light-years away!
Terrestrial planets are the solid planets like Earth and Mars. Jovian planets are those gas planets like Jupiter and Saturn.
