Not exact matches
Comets, after all, spend
most of their time far from their star and have highly
eccentric orbits, which could account for the irregularity of dimming.
Using precise positional data from the National Science Foundation's Very Long Baseline Array (VLBA) and from optical telescopes, Felix Mirabel, an astrophysicist at the Institute for Astronomy and Space Physics of Argentina and French Atomic Energy Commission, and Irapuan Rodrigues, also of the French Atomic Energy Commission, calculated that Scorpius X-1 is not
orbiting the Milky Way's center in step with
most other stars, but instead follows an
eccentric path far above and below the Galaxy's plane.
While the mystery of KIC 8462852's brightness variations is still far from settled, a new study by a team of astronomers that has utilised NASA's Spitzer Space Telescope suggests that the culprit is
most probably a huge swarm of cometary fragments that revolve around the star on highly elongated
eccentric orbits.
Due to Pluto's
eccentric orbit, Neptune at times becomes the
most distant planet from the Sun for a few years.
