It closeness to the sun makes viewing Mercury very difficult, it appears close to the sun in the sky from earth and the glare of the sun comes into play. Its also small, the smallest of the eight planets and we can only see a reduced portion of its surface usually as it orbits insides earths orbit. We see it from the side, with half of it illuminated when it is at the best angle relative to the sun and Earth for viewing.

Why is it so hard for astronemers to learn about mercury?

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.


Why element mercury do not hard when you cold it?

Mercury not hard when you cold it because for it to cold you need it be Mexican so you give it a Taco and Sombrero and then you shoot it with the ultra-wishy-wooshy-woomy-laser-majiggy-alizer and it should be hard, this has a 0.097% chance of working but it's worth a shot!

How much is the axialtilt of mercury?

As far as has been possible to observe so far, Mercury's tilt is listed as "probably zero".In other words, its equator is thought to lie in its orbital plane, and its axis of rotation is thought to be perpendicular to its orbital plane.
