American spacecraft “New Horizons” approaches its cherished goal, the dwarf planet Pluto, in orbit of which automatic interplanetary station must arrive in 2015.
Astronomers have discovered that a dwarf planet 2007 OR10, also known as Snow White, is almost completely covered with water ice.
Astronomers have discovered three small bodies, orbiting the sun near Pluto, on the outer reaches of the solar system. According to astronomers this three newfound bodies, which seem to be more than 250 miles (400 km) wide, are likely big enough to be rounded by their own gravity, which means that they can be dwarf planets like Pluto.
Haumea is a bizarre world shaped like a cigar measuring about 1200 miles it is one of the fastest rotation speeds in the solar system. Recently nternational team of researchers has discovered that 75 percent of Haumea’s surface is covered with crystalline water ice.
Researchers from European Southern Observatory (ESO) using a giant telescope in the Chilean find that Haumea, which is the one of the five dwarf planets of the SolarSystem, and one of its satellites, Hi’iaka, covered with brilliant layer of crystalline ice, formed as a result of the tidal gravitational forces and the decay of radioactive elements that make up these Plutoid.
