Submission + - Kepler Observes Neptune Dance with Its Moons
Liquid Tip writes: NASA's K2 mission has the capability to stare continuously at a single field of stars for months at time. The video shows K2 observations spanning 70 days from November, 2014 through January, 2015 reduced to 34 seconds. During this time some some members of our Solar System are seen passing through the K2 field-of-field, including some asteroids and the giant outer planet Neptune which appears at day 15. A keen eyed observe will also notice an object close orbit around Neptune. It is the large moon Triton which orbits every 5.8 days. The fainter moon Nereid can be seen tracing Neptune’s motion
