Halley's Comet Return

July 28, 2061 at 12:00 AM UTC

Mission Overview

The most famous periodic comet in history will return to the inner solar window. Last seen in 1986, its 2061 appearance will be much better positioned for observers on Earth. Halley’s Comet (1P/Halley) orbits the Sun approximately every 76 years. Its return is a cultural and scientific phenomenon that has been recorded by astronomers for over two millennia. During its 2061 approach, the comet will be on the same side of the Sun as the Earth, making it significantly brighter and more dramatic than its previous appearance. It serves as a celestial time capsule, reminding us of the vast cycles of our solar system.
