It never rains or snows on the Moon because it has no atmosphere. One can generally assume, though, that if a planet has an atmosphere, precipitation will occur at some point.
It does rain on Venus, but the rain is made of sulfuric acid. The rain probably never reaches the ground because it evaporates first in the high temperatures.
(Also, it seems to rain liquid methane on Titan, a moon of Saturn.)
He may easily have seen all of the planets in our solar system at one time or another, but the only one he or anybody else ever walked on is the Earth.
Not that we know of. For all we know, the solar system could of had 99 planets but 90 blew up. Scientists are still researching all they can to do with solar explosions and if our solar system had more planets. Never know.
The planets in our Solar System have existed pretty much as long as the Solar System - about 4.6 billion years. Planets in other, older, solar systems may have existed quite a bit longer - almost as long as the Universe (which is 13.8 billion years old).
It's highly unlikely that Jupiter was the first planet. There's no evidence that Jupiter formed any earlier than other planets in our solar system, and no reason at all to believe that planets in other older solar systems might not have formed long ago.
* It is the only planet known to support life in our solar system * 75% of Earth is water. * It is the largest of the inner planets in our solar system * It's hottest temperature ever recorded was 136 degrees F (about 60 degrees C)
Yes more than you can ever imagine

No matter where it may wander, none of the planets in our solar system ever appears in Ursa Major.
In our solar system, there are eight recognized planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune, and Uranus. The total number of planets outside of our solar system can only be hypothesized, but evidences of new planets are being discovered at an ever increasing rate.
Not that we know of. For all we know, the solar system could of had 99 planets but 90 blew up. Scientists are still researching all they can to do with solar explosions and if our solar system had more planets. Never know.
Pluto is no longer classified as a planet, but as a new type of object called a dwarf planet. There are three planets in out solar system orbiting beyond Pluto: Haumea, Makemake, and Eris. None of these were ever classified as planets. Outside our solar system there are over 1,050 known planets orbiting other stars in the Galaxy. The total number of planets in the Galaxy is estimated to be 100 billion to 400 billion.
The planets in our Solar System have existed pretty much as long as the Solar System - about 4.6 billion years. Planets in other, older, solar systems may have existed quite a bit longer - almost as long as the Universe (which is 13.8 billion years old).
It's possible that alien beings have an interest in other planets in our solar system but I don't know how we would ever know because we live here.
It's highly unlikely that Jupiter was the first planet. There's no evidence that Jupiter formed any earlier than other planets in our solar system, and no reason at all to believe that planets in other older solar systems might not have formed long ago.
no one knows because no one can travel to the edge of the ever-expanding universe
There probably was life on Mars, since evidence of water was discovered on the planet. However, there is no certainty that there was ever any life on Mars or other planets in our Solar System.
gravitational pull..also for all we know is that the universe goes on for ever maybe you meam the solar system?
