Welcome! My name is Kevin Heider. I spend most of my wiki-time with the asteroids and TNOs. My first edit was on 2006-09-04.

NEODys / ASTDys
JPL Small-Body Database Search Engine
Orbital simulation from JPL (Java) / Ephemeris

Articles that I started:
1995 GJ: first known cubewano with an inclination of 22.9°. (Template:Footer TNOList) (TNOs)
(119070) 2001 KP77: Reddest measured B-V color index of any TNO.
2002 TD66: PHA passes near the Earth On February 25, 2008.
118401 LINEAR: Asteroid and main-belt comet (176P).
2907 Nekrasov: Some articles incorrectly state that 2907 will collide with the Earth on December 16, 2880.

Articles I made changes to:
19 Fortuna (Darkoid):Re-write. Update refs, albedo 0.037, surface, APmag.
624 Hektor (Trojan): Update Refs, Albedo 0.025.
619 Triberga: Re-write. 4 year orbit that helped calculate the mass of the moon.
349 Dembowska: Re-write. Unusually high albedo of 0.384 and may have undergone partial melting/differentiation.
433 Eros (NEA):Re-write. (Table) Mag 8.1 in 2012 and mag 7.1 in 2056. (81 year cycles)
APmag:Mars ref, mag, opp; Pluto 13.65; Ceres 6.7 (2012-12-18); 3 Juno mean 8.7; 3753 Cruithne NEA 15.8 (2007-Oct-31); 471 Papagena Infobox
(91133) 1998 HK151: Bluest measured B-V color index of any TNO.
(42301) 2001 UR163: Reddest measured B-R color index of any object in the solar system.
(55636) 2002 TX300: Changed diameter to a 530-709 range, changed albedo, added spectra, and re-worded.
(84522) 2002 TC302: Added spectral_class = red, changed diameter to a 420 - 1190 range, and cleaned-up.
90377 Sedna: Added spectral_class = red (Ref clean-up.) (Talk Sedna Albedo)
Uranus: During the formation of the planets, Uranus collided with an Earth sized protoplanet.
50000 Quaoar: 18.5 magnitude and re-write.
2004 XP14: Changed size, added AU distance and links.
2004 FU162 (Meteoroid): Fixed wiki link to Record-setting close approaches to Earth.
854 Frostia: Changed size and satellite info and added rotation peroid.
List of noteworthy asteroids: Added 118401 LINEAR and 2004 XP14.
3D/Biela: Added some history (Ref clean-up.) 15,000 per hour outburst.
704 Interamnia: Changed to 'fifth most massive asteroid', changed dimensions to 350.4×303.7km, and added many links.
2 Pallas: Is Ceres still an asteroid fallout. Magnitude 6.96 (2014-02-25).
152 Atala: Changed size to a 71-122 range and added many links.
4 Vesta: Added comments about Vesta being differentiated.(How to mark refs)
8 Flora: Added JPL Java simulation and GIF of Nov 15th, 2007 opposition. Magnitude 7.9 (2007-11-18). Image deletion.
38628 Huya: Changed size to 480km and commented on possible dwarf planet status. Update links, wording, opposition.
90482 Orcus: The 1st time someone rv me. :-)
2000 CR105: Changing aphelion to 397AU and size to 265km.
