(90377) Sedna I (disproven moon)

This object does not exist.

This object has been proven to not exist by further study. Please take it lightly and with a grain of salt.

(90377) Sedna I is a now disproven moon that was thought to be orbiting Sedna. Due to Sedna’s slow rotation, a hypothesis of a moon has been thought of. No determined mass, radius, or other proof has been made so far.^[1] It would seem to be either very far away, very close, or has a very low brightness and/or albedo, although no other proof was confirmed or put on the table.

Later Data[]

Soon, new measurements came out that the rotation was actually 10 hours, ruling out most possibilities for a moon around the icy object.^[2]
