Five New Planets Found; Hotter Than Molten Lava - National Geographic Jan 4"Five new planets have been found orbiting distant starsthe first confirmed new worlds from NASA's recently launched Kepler space telescope mission, astronomers announced today. Like many of the more than 400 exoplanetsplanets outside our solar systemfound to date, the new planets are so-called hot Jupiters. They're about the same mass as Jupiter and orbit very close to their host stars, which makes the planets relatively easy to spot from Earth. The smallest of the new planets is about the same size as Neptune, though much more massive. All of the planets are hotter than molten lava and could turn gold to goo, according to NASA temperature estimates. Dubbed Kepler 4b, 5b, 6b, 7b, and 8b, the five new planets range in temperature from 2,000 to 3,000 degrees Fahrenheit (1,090 to 1,650 degrees Celsius), William Borucki, Kepler's principal investigator, said today during a press briefing at the American Astronomical Society's annual meeting in Washington, D.C. One of the worlds, Kepler 7b, is among the lowest-density planets yet found, with about the same density as Styrofoam, he said."...Chart of Planet Size and Temperature
