Second Oddball Planet Found That Orbits Backwards

August 14, 2009

(ChattahBox)—Just days after a first-of its-kind discovery, by two graduate students, of a backwards orbiting planet in the distant galaxy, another backwards planet was found by a team of Japanese astronomers.

A large gas planet, named WASP-17b was first spotted from the Geneva Observatory, orbiting around its host star in the opposite direction about 1,000 light-years away from Earth. The discovery of WASP-17b would not remain a first for long.

A team of Japanese scientists from the National Astronomical Observatory of Japan, led by Joshua Winn of MIT and Norio Narita of the Observatory, discovered a backwards planet of their own, named HAT-P-7b, that is also about 1,000 light-years away and orbits its star in the direction opposite to its star’s own rotation.

Winn called the coincidence of two backwards-orbiting planets discovered within a few days of each other as, “funny.”

Both teams of astronomers have submitted their findings to be published in peer review journal.

    Correction: 1000 light years is not “the distant galaxy.” It’s practically next door for cosmic distances. Out galaxy, the Milky Way, is some 100,000 light years across.
