In comparison, Mars received its first orbiter in 1971 and Venus in 1975. Jupiter, at its closest nearly 630 million kilometers (390 million miles) away from Earth compared to Mercury’s average 77 million kilometers (48 million miles), welcomed its first orbiter in 1995. Even the more dis...

The surface temperatures on Venus are approximately 900°F (475°C), which is hot enough to melt lead. Compare this to the temperature on Mercury, which gets as hot as roughly 800°F (430°C). The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without ...
13、y long daytime (88 Earth-days long), the temperatures are very high (the second-highest in the Solar System - only Venus is hotter); during the long night, the thin atmosphere lets the heat dissipate, and the temperature drops quickly.MOONSMercury has no moons.MERCURY-EARTH COMPARISONS...
The temperature on Venus is slightly hotter but very stable.Mercury is in many ways similar to the Moon: its surface is 13、heavily cratered and very old; it has no plate tectonics. On the other hand, Mercury is much denser than the Moon (5.43 gm/cm3 vs 3.34).Mercury is the second...
Current A second NASA mission to Mercury, named(MErcury Surface, Space ENvironment, GEochemistry, and Ranging), was launched on 3 August 2004. It made a fly-by of Earth in August 2005, and of Venus in October 2006 and June 2007 to place it onto the correct trajectory to reach an orbit...
Temperature variations on Mercury are the most extreme in the solar system ranging from 90 K to 700 K. The temperature on Venus is slightly hotter but very stable. Mercury is in many ways similar to the Moon: its surface is heavilycratered17and very old; it has no plate tectonics. On ...
s oceans. Thick sulfuric clouds downpour constant acid rains on the surface that are immediately evaporated. The winds at the surface are slow but they are carrying around considerable amount of dust and rocks. However the atmosphere of Venus is layered and at about 50-65 km above the surface...
Although the temperature on Venus is slightly hotter, it is very stable.Mercury has no known satellites. It is in many ways similar to the Moon: its surface is heavily spread with holes and is very old. On the other hand, Mercury is much denser(密度大的) than the Moon. Mercury is ...
