Astronomers Discovered First Four Exoplanets of 2012

Only four days into the New Year and the first four exoplanets of 2012 have been spotted orbiting four distant stars. All four alien worlds are known as hot Jupiters, large gas giant planets orbiting very close to their stars. Their orbits are aligned just right with the Earth so that when they pass in front of their parent stars, they slightly dim the starlight from view. This four exoplanet called HAT-P-34b, HAT-P-35b, HAT-P-36b and HAT-P-37b have very tight orbits around their stars, completing a year”in only 5.5, 3.6, 1.3 and 2.8 days respectively. Remembe, that Earth orbits the sun every 365 days. All this exoplanets were found by astronomers at the Harvard-Smithsonian Center for Astrophysics which operates a network of ground-based telescopes known as the HATNet project. The first exoplanet discovery by HATNet, the planet HAT-P-1b, was in 2006.
