While the Andromeda Galaxy contains about 1 trillion (1012) stars and the Milky Way contains about 300 billion (3×1011), the chance of even two stars colliding is negligible because of the huge distances between the stars.
Mens Andromedagalaksen indeholder omkring 1 billion (1×1012) stjerner og Mælkevejen indeholder 300 milliarder (3×1011), er sandsynligheden for, at to stjerner kolliderer, ubetydelig på grund af de enorme afstande mellem stjernerne.
