Science How does a comet change when it comes close to the sun? Asked by Dr. John Carmen 13 years ago 1/10/2013 7:22 AM Last updated by anonymous 13 years ago 1/11/2013 4:45 PM
The comet loses some of its ice (vaporizes) and dust particles escape into space. The solar wind pushes gas and dust, which is what causes the comet's tail to form.
