Pictures of Mercury, the closest planet to the Sun: Core Orbit

Planet Mercury is the planet that is considered as the closest to the sun and orbits the star for about an average distance of 57.9 million km. It can make a complete trip around the sun for a period of 88 days. Now that Planet Pluto is already referred to as a dwarf planet, Mercury

Mercury is the planet that is closest to the sun. It is also the smallest. These two factors make it hard for experts to thoroughly probe Mercury. So far, only two spacecrafts have flown to Mercury to collect data: the Mariner 10 in 1974 and the MESSENGER spacecraft in 2008. Still, even with these two

Mercury, the smallest planet in the Solar system, is classified as a terrestrial planet along with Earth, Venus, and Mars. The surfaces of these terrestrial planets are composed of silicate rocks and these planets are classified in a group called inner planets. Mercury and other inner terrestrial planets are made up of a metallic core

Mercury is the planet closest to the sun and is the smallest planet in the solar system. It is so small that some natural satellites exceed its size like Jupiter’s Ganymede and Saturn’s Titan. However, Mercury possesses more mass than both Ganymede and Titan. Despite its size, it is only second to Earth in density

The Solar System’s smallest and innermost planet is Mercury, named after the messenger and god of trade in Roman mythology (also known as Hermes in Greek mythology). Being the innermost planet, probing and observing Mercury is difficult, although it has been done. In fact, Mercury is actually part of the five classical planets, together with

The atmosphere of Mercury is a tenuous exosphere that contains varying elements. The elements contained in Mercury’s exosphere are helium, hydrogen, oxygen, sodium, calcium, potassium and water vapor. The comet-like tail that is seen on the end of the planet is created by atmospheric gasses that are pushed by solar light. Sodium is the primary

Mercury is the innermost planet in the Solar System, but surprisingly it is not the hottest planet; that would be Venus. The reason for this is that Mercury has a thin atmosphere that cannot trap solar heat. Its maximum atmospheric pressure is estimated to be 0.00000000003 pounds per square inch; on Earth, the atmospheric pressure

The planet with the most eccentric orbit in the Solar System is Mercury. The eccentricity for the planet is 0.21 and its distance from the sun ranges from 46-70 million kilometers. It only takes 88 days for Mercury to orbit around the Sun at 47.8 km/sec (29.7 miles/sec). A typical year on Mercury would take
