IC 417 (also known as Sh2-234) is an emission nebula of almost 100 light-years across, located some 10,000 light-years away from Earth in the constellation of Auriga (the Charioteer). It is often referred to as the Spider Nebula and its prey is an emission nebula called the Fly (NGC 1931) located nearby.

The nebula contains a young open cluster of about 40 stars, and is energized by its hot, massive blue stars which are still embedded in glowing hydrogen gas.
