Sombrero Galaxy is a
spiral galaxy in the
Virgo constellation. It was discovered in the late 1700s. It is about 28 million
light years away and is just faint enough to be invisible to the naked eye but easily visible with small telescopes. In our sky, it is about one-fifth the diameter of the
full moon. M104 is moving away from
Earth at about 1,000 kilometers per second.
