... October 2, 1999 . Phi Persei: Double Star . ... Based on recent results , this artist's vision of the double star Phi Persei , 720 light years away, shows a bright, rapidly rotating massivestar surrounded by a disk of gas. A small companion star orbits 100 million miles away. ... Ten million years ago the small companion was actually the most massivestar in the system and because of its greater mass evolved into a giant star more quickly. ... About APOD > . ...

... Here is a brief outline of the current theory of the events in the early history of the solar system: . A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. ... The gas cools off enough for the metal, rock and (far enough from the forming star) ice to condense out into tiny particles. (i.e. some of the gas turns back into dust). ... Once the larger of these particles get big enough to have a nontrivial gravity, their growth accelerates. ...
