Ten bodies in the solar system larger than 200 miles in diameter:

- Sedna (Trans-Neptunian Object, 918 mi.)
- 2006 QH181 (TNO, 475 mi.)

- 2004 UX10 (TNO, 328 mi.)
- Mars (Terrestrial planet, 4204 mi.)
- Triton (Neptunian moon, 1678 mi.)

There's a neat picture showing these ten bodies and the other 78 known bodies in the solar system larger than 200 miles in diameter here. Definitely worth a look, though you'll need to be patient if you're on dial-up.
