ウェイウォット ((50000) Quaoar I Weywot) is a satellite of solar system circumference heavenly bodies (50000) クワオアー. It is Michael Braun and T.-A. from a photograph photographed on February 14, 2006 by the Hubble Space Telescope Suer discovered it and was announced in International Astronomical Union answer (IAUC) 8812 of February 22, 2007.

This satellite was discovered in クワオアー at a remote place for 0.35 seconds, and the brightness was different in 5.6. As for the diameter, it is thought that I suppose that albedo is the same as クワオアー with 95+-24km. クワオアー loses most of the mantles of the ice by the collision with other heavenly bodies in the past, and Brown thinks that ウェイウォット was formed from the piece which I produced by the collision.

The name comes from ウェイウォット of heavens God in the first sons of Demiurge クワオアー coming up in the myth of the トングヴァ group. Brown suggested it and was announced with asteroid center answer (MPC) of October 4, 2009 67220 [2].
