XO-1 (also known as "GSC 02041-01657") is a yellow dwarf star approximately 600 light-years away in the constellation Corona Borealis. XO-1 has a mass and radius similar to the Sun. In 2006, an extrasolar planet (XO-1b) was discovered orbiting XO-1. This was done by the XO Telescope.

Planetary system

In 2006, an international team of professional and amateur astronomers discovered a Jupiter-sized planet orbiting around XO-1. The team, led by Peter McCullough of the Space Telescope Science Institute in Baltimore, includes four amateur astronomers from North America and Europe.

The planet was confirmed using the Harlan J. Smith Telescope and Hobby-Eberly Telescope at McDonald Observatory of the University of Texas.
