Size and Mass: With a mean radius of 2440 km, Mercury is the smallest planet in our Solar System, equivalent in size to 0.38 Earths. It is unlikely that life as we know it could survive on Mercury due to solar radiation, and extreme temperatures. A planet in an unlikely orbit around a double star 336 light-years away may offer a clue to a mystery closer to home: the hypothesized "Planet Nine.". JPL is a division of the California Institute of Technology in Pasadena. Dec 9, 2011: NASA's Dawn spacecraft spent the last four years voyaging to asteroid Vesta â and may have found a planet. The smallest planet in regards to both mass and volume is Mercury â at 4,879 km across and 3.3010 x 10 23 kg, this tiny world is nearly 20 times less massive than Earth, and its diameter is about 2½ times smaller.

NASA's Dawn probe, now orbiting Vesta in the asteroid belt, has found some surprising things on the giant asteroid--things that have prompted one researcher to declare Vesta "the smallest terrestrial planet.". Mercury doesn't really have an atmosphere. It has a diameter of about 31,518 miles. 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 four planets closest to the sunâMercury, Venus, Earth, and Marsâare called terrestrial planets. Mercury is the fastest planet in our solar system – traveling through space at nearly 29 miles (47 kilometers) per second. False colors in this montage denote topography, where the colors indicate heights ranging from -22 km to +19 km above a reference ellipsoid.
