About 4 billion years ago, an asteroid roughly 60 miles kilometers wide struck Mercury with an impact equal to 1 trillion 1-megaton bombs, creating a vast impact crater roughly miles 1, km wide.

Known as the Caloris Basin, this crater could hold the entire state of Texas. The tiny planet is made up of a single continental plate over a cooling iron core. The combination of its massive core and abundance of volatile elements has left scientists puzzled for years. A completely unexpected discovery made by Mariner 10 was that Mercury possessed a magnetic field.

Planets theoretically generate magnetic fields only if they spin quickly and possess a molten core.

Instead of a substantial atmosphere, Mercury possesses an ultra-thin "exosphere" made up of atoms blasted off its surface by solar radiation, the solar wind and micrometeoroid impacts. These quickly escape into space, forming a tail of particles. Its oval-shaped orbit is highly elliptical, taking Mercury as close as 29 million miles 47 million km and as far as 43 million miles 70 million km from the sun.

If one could stand on Mercury when it is nearest to the sun, it would appear more than three times as large as it does when viewed from Earth.

Mercury is the closest planet to the sun and has a thin atmosphere, no air pressure and an extremely high temperature. Take a look inside the planet. At sunset, the sun appears to set, rise again briefly, and then set again.

Ina rare transit of Mercury happenedwhere the planet crossed the face of the sun. Iron core roughly 2, to 2, miles 3, to 3, km wide. Outer silicate shell about to miles to km thick.

Perihelion closest approach to sun: If so, it would make the rocky planet a member of a very select club with samples available on Earth; only the moon, Mars and the asteroid belt have verified rocks. Inscientists released the first-ever global digital-elevation model of Mercurywhich combined more than 10, images acquired by MESSENGER to take viewers across the wide-open spaces of the tiny world.

Additional reporting by Nola Taylor Redd, Space."It followed us during half of our orbit. We observed it on the light side, and when we entered the shadow side, it disappeared completely.

It was an engineered structure, made from some type of metal, approximately 40 meters long with inner hulls. Mercury is the smallest and innermost planet in the Solar System.

Spotting it could prove quite challenging, but if you plan ahead and observe from a location with a good horizon without obstructions (such as trees or buildings), you should be able to see it. BepiColombo is Europe's first mission to Mercury. It will set off in on a journey to the smallest and least explored terrestrial planet in our Solar System.

Mercury is the closest planet to the Sun. Mercury is slightly smaller in diameter than the moons Ganymede and Titan but more than twice as massive. Planet Profile. orbit: 57,, km ( AU) from Sun diameter: 4, km mass: e23 kg. .
