2025 RationalWiki 'Oregon Plan' Fundraiser

There is no RationalWiki without you. We are a small non-profit with no staff—we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.

Fighting pseudoscience isn't free.
We are 100% user-supported! Help and donate $5, $10, $20 or whatever you can today with PayPal Logo.png!

Category:Dwarf planets

From RationalWiki
Jump to navigation Jump to search

A dwarf planet, as defined by the International Astronomical Union (IAU), is a celestial body orbiting its star that is massive enough to be rounded by its own gravity but has not cleared its neighboring region of planetesimals and is not a satellite. Because the Earth has a trojan called 2010 TK7, it has not cleared its orbit, so Earth is also a dwarf planet by the IAU definition.
