Mercury Poster Version A Nasa Solar System Exploration Mercury is the fastest planet in our solar system – traveling through space at nearly 29 miles (47 kilometers) per second. the closer a planet is to the sun, the faster it travels. 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. Mercury is the second densest planet, after earth. it has a large metallic core with a radius of about 1,289 miles (2,074 kilometers), about 85 percent of the planet's radius. there is evidence that it is partly molten or liquid. mercury's outer shell, comparable to earth's outer shell (called the mantle and crust), is only about 400 kilometers.

Our solar system orbits the center of the galaxy at about 515,000 mph (828,000 kph). it takes about 230 million years to complete one orbit around the galactic center. we call it the solar system because it is made up of our star, the sun, and everything bound to it by gravity. Nasa’s solar system interactive (also known as the orrery) is a live look at the solar system, its planets, moons, comets, and asteroids, as well as the real time locations of dozens of nasa missions. Introduction. the planetary system we call home is located in an outer spiral arm of the milky way galaxy. our solar system consists of our star, the sun, and everything bound to it by gravity – the planets mercury, venus, earth, mars, jupiter, saturn, uranus, and neptune; dwarf planets such as pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.
