alileo discovered mercury in the late sixtenth century but wasnt proven a planet until 1639
Galileo DID NOT discover Mars. Mars has always been visible from Earth to the unaided human eye and was known to and named by our ancient ancestors. Galileo is believed to be the first person to view Mars though a telescope in 1609.
The first person to see Mercury with a telescope is believed to be Galileo Galilei in the early 17th century. He observed the phases of Mercury, similar to those of the Moon, which supported the heliocentric model of the solar system.
Please do not answer if you are quessing. I see many wrong answers on this site. Galileo does not have mercury in it. It is water and a light weight petroleum mixure. Also, glass thermometers no longer have mercury.
That might be an indication that Mercury has a similar composition to Earth. For more details, check the Wikipedia articles on Earth, and Mercury, to see what is believed to be inside each planet.
In order from the Sun, you see Mercury, Venus, Earth and Mars. Then there is a gap, which happens to be roughly where the Asteroid Belt is. Then Jupiter, Saturn, Uranus and Neptune.

Mercury [See Link] was a messenger and the Roman God of commerce and thievery.
Mercury is not the coldest planet because it has more solar radiation than all of the other planets. This is because it is closer to the Sun. However, Mercury is not the hottest planet in the Solar System. See related question.
The planet which is the nearest to the Sun is Mercury, which also happens to be the smallest planet in our Solar system.
Because its too far away.

The planet "Mercury" is the first planet in our solar system. It is the closest to the sun. Usually Mercury is almost impossible to see because the Sun's glare blinds us to it. It is 57.9 Million Kilometers from the sun with a surface temp ranging between -180 to +430 Celsius. It takes 87.97 Days to orbit the sun and it has no moons.
