A Strange Green Comet Is Heading Toward Earth!
An unusual green comet reaches maximum brightness to our sky providing a sweet treat for early-morning risers.
Comet 45P/Honda-Mrkos-Pajdusakova travels into the inner solar system every 5.25 years. On Saturday, 45P will pass just 7.4 million miles from Earth, a stone's throw by celestial yardsticks.
Comet 45P will look like fuzzy bluish-green ball with a fan-shaped tail. Its distinctive color comes from vaporizing diatomic carbon, a gas which glows green in the near-vacuum of space. "The comet will be racing through the constellation Hercules high in the eastern sky!
The Minor Planet Center reports 45P's upcoming pass as the eighth closest comet since modern tracking technologies began around 1950. It made an even closer approach during its last visit in 2011, pictured above, but it won't be as near to Earth again this century.
