Because its too far away.
Mercury is A planet that nobody has been on it is far to hot. Plus it can get up to over many degrees C or F and Mercury is a gas planet so even the stuff on Mercury has a hard time sheilding it's way from the sun.
mercury is hard to see from the earth because it is so close to the sun. it is best to view mercury either at sun rise or sun set.
Planet Mercury doesn't have an atmosphere so it cannot have hurricanes.
Mercury is the smallest planet, so there isn't one with half the diameter.
No. Mercury orbits the sun, so it is a planet rather than a moon.
Only one planet mercury so I guess that makes it rare
Mercury is closest to the sun. There are so many rocks ,we can't live in that planet.
it is hard because it is so far in the sky and it is far away in the sky and you have trouble seeing it
You can see it just before sunrise and just after sunset depending on the relative positions of the Earth and mercury. It is very close to the sun so you will need to know when and where to look
Mercury is the closest planet to the Sun, and MUCH closer to the SUN than the Earth so whenever we (astronomers or anyone from Earth) observe Mercury, we are looking almost directly at the Sun. Even when the Sun is not behind Mercury (from our perspective), we are still looking through all the light, radiation, and electromagnetic interference between the Earth and Mercury. This makes observing Mercury very hard, even with the latest in technology, because the interference is intense due to Mercury's close proximity to the Sun. The only way to get accurate readings (free from the Sun's interference) is to put a satellite in orbit around Mercury. This was finally accomplished in 2011 when the MESSENGER satellite began mapping the surface of Mercury.
Mercury has a surface, so yes you could stand on it.
