Retrograde Object R631 Orbits Sun
Tap title to read story
Scientists believe a close encounter with Neptune may have sent the object into its backward orbit around the Sun.
Deep in the outer reaches of the solar system, an unusual object is moving against the flow of cosmic traffic, cutting across the Sun’s orbital plane at a remarkably steep angle.
The Rubin Observatory in Chile first spotted the object beyond the orbit of Neptune at a distance of approximately 3 billion miles (4.8 billion kilometers).
While most planets, asteroids, and comets orbit the Sun in a relatively flat plane, this newly discovered object follows a retrograde path defined by a highly inclined orbit.
