Mercury

Mercury (Michael Mak)




 * ==**Orbital Period:**==
 * The orbit of Mercury is the most eccentric of the planets in our Solar System.
 * The planet has an orbital 87.969 Earth days
 * 57,910,000 km (0.38 AU) from Sun. Orbiting the Sun once every 88 days.
 * ==**History**==
 * Mercury has been known since ancient times.
 * Until the mid-1960's, astronomers believed that Mercury rotated once every 88 Earth days, the same time the planet takes to go around the sun.
 * If Mercury did this, one side of the planet would always face the sun and the other side would always be dark. However, radar studies conducted in 1965 showed that the planet rotates once in about 59 days.
 * The only spacecraft to come close to Mercury was Mariner 10 from 1974 to 1975, which was only able to map 40% to 45% of the planet's surface.
 * ==**‍Mythology**==
 * The mythology of Mercury begins back in Babylonian times where Mercury was known as Nebo (Nebu)
 * Nebu mythology of Mercury begins back in Babylonian times where Mercury was known as Nebo (Nebu).
 * Nebo became the scribe of the gods. It was his job to write down the laws and edicts of Marduk and to communicate them to men.
 * Marduk later became the Greek Zeus and then the Roman Jupiter. Nebo became the Greek Hermes and then the Roman Mercury.
 * ==**Size**==
 * Mercury is the smallest planet in the Solar System by surface area, volume, and equatorial diameter.
 * Surprisingly, it is one of the most dense. It gained its ‘smallest’ title after Pluto was demoted. That is why older material refers to Mercury as the second smallest planet.
 * The aforementioned are the three criteria that we will use to show the size of Mercury in relation to Earth.
 * Mercury has a surface area of 7.48×107 km2. That is 10.8% of the surface area of Earth. Mercury would be smaller than some continents on our planet, if you laid it out flat.
 * ==**Composition**==
 * Mercury composition is made up of approximately 70% metals and 30% silicate material. In fact, it’s only slightly less dense than the Earth, with 5.43 g/cm3.
 * Since Mercury is smaller than Earth, its gravity doesn’t compress it down as much, so it actually has much more heavier elements inside it.
 * Geologists estimate that its core is very large, and mostly iron. The core probably accounts to 42% of Mercury’s volume, while Earth is just 17%.
 * ==**Atmospheric conditions**==
 * There were no any air on mercury
 * hot and hostile
 * ==**Significant & noteworthy features**==
 * One of Mercury's most noteworthy features is its contribution to physics
 * It helped validate one of science's most breakthrough theories
 * Mercury follows a seemingly erratic orbit
 * It is as close as 29 million miles to the Sun, and as far away from it as 43 million miles.
 * ==**What don’t we know?**==
 * Half of Mercury had never been seen.
 * It has the most eccentric orbit of all the planets
