The view from out there, how the solar system looks to aliens

Wednesday, 29 September, 2010

Thanks to tracks created by outermost planet Neptune (if you accept that Pluto is no longer classed as a planet that is) in the dust of the Kuiper belt – a very large Asteroid belt like collection of frozen objects that reside on the edge of the solar system – astronomers on alien worlds should be able to detect the presence of the Sun’s planetary system:

“The planets may be too dim to detect directly, but aliens studying the solar system could easily determine the presence of Neptune – its gravity carves a little gap in the dust,” Goddard astrophysicist Marc Kuchner said in a press release yesterday. “We’re hoping our models will help us spot Neptune-sized worlds around other stars.”
