- A team of researchers spotted a close pair of trans-Neptunian objects
- The unusually close pair was also occulting a binary star system
- The discovery was made with the help of a citizen science project
With the help of a citizen science research network, a team of researchers has discovered an unusual pair of trans-Neptunian objects (TNO).
Any object in our solar system that has an orbit beyond Neptune is considered a TNO. According to NASA’s Jet Propulsion Laboratory (JPL), there are about 70,000 known TNOs, including Pluto, each measuring at least 100 kilometers (62.137 miles) across.
In a new study, published in The Planetary Science Journal, a team of researchers discovered a TNO pair orbiting each other. The researchers discovered them using a stellar occultation, which occurs when the light of a star is blocked by an object from reaching the observer, a news release from the
