Carbon-Rich Exoplanet in Auriga

Post by Christopher K. »

WASP-12b is a 1.4-Jovian mass exoplanet approximately 1200 light years away in the constellation Auriga. It was discovered with Spitzer images and observations with the Canada-France-Hawaii Telescope at Mauna Kea. It is the first exoplanet to have a calculated carbon-to-oxygen ratio greater than one. Its atmosphere includes carbon monoxide and methane but not much water vapor. It is conceivable that the surface contains abundant amounts of diamond, graphite and tar.

WASP-12b orbits its yellow, G-class star every 1.1 Earth days. Due to its close proximity to the star, WASP-12b is slightly egg-shaped. WASP stands for "Wide Angle Search for Planets".

Spitzer ran out of coolant in May 2009 and is now conducting its "warm mission".

When people my age were kids, the idea of planets orbiting other stars was conjecture. Many thought it was likely as already we were familiar with one star that had them, but there was no proof. Over the past recent years, we've accumulated that proof and unlocked whole new section of galactic inquiry.

"The Search for Another Planet" is a half-hour program offered by NASA-TV this week at the following Central Daylight times...
