Why does a comet's tail point away from the Sun? 1Choice 1 The solar wind blows the tail away from the Sun. 2 It is being pulled by a nearby black hole. 3 The Moon's light only shines on part of the comet. 4 The comet's tail is following the path of Jupiter.
The Sun's radiation and solar wind cause the dust and gas around the comet (coma) to stretch the coma. The solar wind electromagnetically blows the ions in the coma away.
