It may not be quite the 'Comet of the Century' predicted to light up the sky later this year, but it could still be spectacular.
A comet that shines as brightly as the stars of the Big Dipper will pass in front of the Earth in March.
The Comet Pan-Starrs will pass through our solar system at about 100 million miles from the Earth, Nasa scientists have said.

How comets react to the sun is difficult to predict. Researchers think it may either fall apart - and put on a short, "dazzling" show - or else slowly combust, producing a long bright tail in the process.
Either way the comet looks set to dazzle astronomers - and possibly anyone looking at the night sky with the naked eye - when it completes its journey from the outer reaches of the solar system.
"Because of its small distance from the sun, Pan-Starrs should be very active, producing a lot of dust and therefore a nice dust tail," said astronomer Matthew Knight of the Lowell Observatory in a release.
The comet was discovered in June 2011 by the Panoramic Survey Telescope & Rapid Response System.
Meanwhile the Comet Ison is expected to shine even more brightly when it passes close to the Sun in November.
