Pleiades Meets Uranus

This image shows a close approach between the Pleiades star cluster (M45) — also known as the Seven Sisters — and the distant planet Uranus, visible as a faint greenish dot below the cluster.

Uranus lies at an average distance of about 3 billion kilometers (19.2 AU) from the Sun. It is roughly four times larger than Earth and completes one orbit around the Sun every 84 Earth years. Because of its faint brightness (magnitude ~5.7 at best), Uranus is generally not visible to the naked eye and usually requires binoculars or a small telescope to spot. Its bluish-green color comes from methane gas in its atmosphere, which absorbs red light and reflects blue-green light.

This close approach is still visible these days, offering skywatchers a rare chance to observe Uranus alongside one of the most iconic deep-sky objects.
