3353 Jarvis, or by its provisional designation,1981 YC, is a carbonaceous Hungariaasteroid,slow rotator and suspected tumbler from the inner regions of theasteroid belt, approximately 10 kilometers in diameter.
It was discovered on 20 December 1981, by American astronomerEdward Bowell at Lowell'sAnderson Mesa Station near Flagstaff, Arizona, and named afterGregory Jarvis, who died in theSpace ShuttleChallenger disaster.[2][3]
Jarvis is a member of theHungaria family, which form theinnermost dense concentration of asteroids in theSolar System. It orbits the Sun at a distance of 1.7–2.0 AU once every 2 years and 6 months (929 days). Its orbit has aneccentricity of 0.08 and aninclination of 22° with respect to theecliptic.[1] A firstprecovery was taken at theSiding Spring Observatory in 1980, extending the body'sobservation arc by more than one year prior to its official discovery at Anderson Mesa.[3]
In July 2007, a rotationallightcurve of Jarvis was obtained from photometric observations by astronomerBrian Warner at his Palmer Divide Station, Colorado, in collaboration withRobert Stephens, Alan Harris andPetr Pravec. The re-examined lightcurve analysis gave arotation period of 202 hours with a brightness amplitude of 0.50 inmagnitude, superseding the original period solution of 40.8 hours (U=2+/2).[12][a]
Due to an improved long-term calibration of the obtained photometric data points, a much longer period of 202 hours has been derived for Jarvis, which is now among theTop 300 slowest rotators known to exist, as most minor planets have spin rates between 2.2 and 24 hours only.[12]
The observations also suggest that Jarvis might be a tumbling asteroid in a non-principal axis rotation, which are typically slow rotators (T0).[4]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite, and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission, Jarvis measures between 9.72 and 12.49 kilometers in diameter, and its surface has analbedo between 0.030 and 0.074.[5][6][7][8][9][10] TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.0622 and a diameter of 9.70 kilometers based on anabsolute magnitude of 13.7.[4]
While most members of the Hungaria family areE-type asteroids with extremely bright surfaces and albedos in the order of 0.30, Jarvis has an unusually low albedo,[clarification needed] typically seen forcarbonaceous asteroids.
Thisminor planet was named in memory ofGregory Jarvis (1944–1986), American astronaut and payload specialist, who died in theSpace Shuttle Challenger disaster on 28 January 1986.[2] The asteroids3350 Scobee,3351 Smith,3352 McAuliffe,3354 McNair,3355 Onizuka, and3356 Resnik commemorate the other crew members. The approved naming citation was published by theMinor Planet Center on 26 March 1986 (M.P.C. 10550).[14]
