Though Mercury's magnetic field at the surface has just 1% the strength of Earth's, it interacts with the magnetic field of the solar wind to sometimes create intense magnetic tornadoes that funnel the fast, hot solar wind plasma down to the surface of the planet. Two NASA missions have explored Mercury: Mariner 10 was the first to fly by Mercury, and MESSENGER was the first to orbit. 14 How far away from the Sun is each planet? But a year on Mercury goes fast. The closest planet to Earth in our solar system is the planet Venus, yet sometimes Mercury may also be closer. The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth's Moon. What Is The Closest Planet To Earth? - WorldAtlas It is unlikely that life as we know itcould survive on Mercury due to solar radiation, and extreme temperatures. Space agencies often use gravitational boosts from other planets to gain speed without a high fuel cost. (Venus' transits are significantly more rare, occurring only once every 243 years.). Only Earth can be assigned AU 1. Seasons are caused by a tilt in the axis. Despite being the smallest planet, Mercury affords rich opportunities for observation and study and, hopefully, future visits. At its closest, it is 48 million miles from Earth; at its furthest, it is 138 million miles from Earth. About 18 copies of the planet would fit inside ours, as it's only about the width of the Atlantic Ocean. Friday, June 3, 2016, dawn. The constant motions of planets around the sun means that the distance between Earth and Mercury is in constant flux. Because of Mercury's elliptical egg-shaped orbit, and sluggish rotation, the Sun appears to rise briefly, set, and rise again from some parts of the planet's surface. The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth's Moon. The space environment dust impacts and solar-wind particles causes the rays to darken with time. Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system - 88 days. Mercury lies an average of 56.97 million miles from Earth and 36 million miles from the Sun. 21 Does Mercury have a nickname? That means it spins nearly perfectly upright and so does not experience seasons as many other planets do. About 18 copies of the planet would fit inside ours, as its only about the width of the Atlantic Ocean. Mercury's surface resembles that of Earth's Moon, scarred by many impact craters resulting from collisions with meteoroids and comets. One AU is the mean distance from the center of the Earth to the center of the Sun. Some of the components of the exosphere are elements like helium from the surface spewed off from the radioactive decay of planetary elements. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. First Look at Mercury's Previously Unseen Side 4 . The terrain is full of craters (large and small). Moore Boeck, A 3D model of Mercury, the innermost planet. Mercury, on the other hand, appears dark grey due to the graphite in its crust (the same substance as pencil lead). 13 How far away is Mercury from Earth? While Mercury has no liquid water, it does have water ice at its perpetually shadowy poles, similar to Earths polar regions. . It gets weirder the same principle holds true for all the planets. The total straight line distance between Earth and Mercury is 8617 KM (kilometers) and 900. Both planets formed around the same time, approximately 4.5 billion years ago. Mercury has had an unfair share of bombardment by numerous bodies in its billions of years of existence because it has no atmosphere to protect its surface.
