Naming

M.P.C. 75547).[5]
Classification and orbit
Vishnu orbits the Sun at a distance of 0.6–1.5
precoveries were taken, and no prior identifications were made, the body's observation arc begins with its official discovery observation at Palomar in 1986.[2]
Vishnu is a
lunar distances.[1]
Its highly eccentric orbit crosses the orbits of all inner planets except that of Mercury, which effectively makes it a
Mars-crosser all at once. From 1800 to 2200, Vishnu has made and will make multiple approaches of Venus (71×), Earth (29×), and Mars (7×) within 30 gigameters. It has been observed by radar astronomy (Binzel) and the orbital solution includes non-gravitational forces.[1]
Physical parameters
In the
3628 Boznemcová, which is the best asteroid match to the spectra of L6 and LL6 ordinary chondrite meteorites. These L and LL chondrites have lower iron metal content, but higher iron oxide content in the silicates.[1]
In the early 2000s, Vishnu has been observed in the thermal-infrared by the
lightcurves have yet been obtained.[6]
