Made up of rock and iron, this planet is thought to be tidally locked to it's parent star (meaning one side always faces the star), it is also much closer to it's host star than the Earth is to the Sun. This means that the "day" side of the planet is always molten, and that's just awesome.
Scanning the heavens, you might very well miss the star Kepler-62. It's a rather typical star, slightly smaller, cooler, and more orange than the Sun, much like tens of billions of other stars in our galaxy. But it holds a surprise: It's orbited by at least five planets… and two of them are Earth-sized and orbit the star in its habitable zone!
The sprawling Caloris basin on Mercury is one of the solar system's largest impact basins, created during the early history of the solar system by the impact of a large asteroid-sized body. The multi-featured, fractured basin spans about 1,500 kilometers in this enhanced color mosaic based on image data from the Mercury-orbiting MESSENGER spacecraft. Mercury's youngest large impact basin, Caloris was subsequently filled in by lavas that appear orange in the mosaic. Craters made after the flooding have excavated material from beneath the surface lavas. Seen as contrasting blue hues, they likely offer a glimpse of the original basin floor material. Analysis of these craters suggests the thickness of the covering volcanic lava to be 2.5-3.5 kilometers. Orange splotches around the basin's perimeter are thought to be volcanic vents.
Whatever you call may call it, Ceres is one of the most geologically interesting and strange objects in the solar system. Its shape, size and composition—round, roughly the size of Texas and at least 20 percent water ice—place it at the poorly understood transition point between rocky worlds like Earth and icy worlds like Jupiter’s Europa, Saturn’s Enceladus, and other large moons of the outer solar system. Other than blurry Hubble Space Telescope images from 2004, its surface had scarcely been glimpsed until Dawn’s approach. As the spacecraft’s ion engines slowly push it toward Ceres, the dwarf planet’s details are now coming into focus, revealing tantalizing new details with practically every new image.
