“(6037) 1988 EG”的意思、由来-开放百科全书

The S-type asteroid orbits the Sun at a distance of 0.6–1.9 AU once every 1 years and 5 months (523 days). Its orbit has an eccentricity of 0.50 and an inclination of 3° with respect to the ecliptic.

The asteroid has an Earth minimum orbit intersection distance (MOID) of {{convert|0.0243|AU|km|abbr=on|lk=off|sigfig=2}}. In combination with its size, this makes it a potentially hazardous asteroid, which require an intersection distance with Earth of less than 0.05 AU, which is about 19.5 times the distance to the moon, and a diameter of at least 150 meters. On 27 February 2041, it will pass {{convert|0.02437|AU|km|abbr=on|lk=off}} from Earth. It also makes close approaches to Mars and Venus.

Physical characteristics

Lightcurve

An ambiguous lightcurve was obtained through photometric observations by Czech astronomer Petr Pravec in 1998. The light-curve gave a rotation period of {{val|2.760|0.002}} hours with a brightness amplitude of 0.20 in magnitude. The alternative period solution is {{val|2.919|0.22}} hours with an amplitude of 0.22 in magnitude ({{small|U=2}}).{{efn|name=Pravec-1998-lcdb}}

Diameter and albedo

The Collaborative Asteroid Lightcurve Link (CALL) assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 540 meters, based on an absolute magnitude of 18.7.^[5] Observations with the Spitzer Space Telescope using its Infrared Array Camera at wavelengths between 3.6 and 8.0 micrometers, gave an average diameter of 399 meters with a higher albedo of 0.37.^[4]
