(6037) 1988 EG, is an eccentric, stony asteroid, classified as near-Earth object and potentially hazardous asteroid. It belongs to the group of Apollo asteroids and measures approximately half a kilometer in diameter. It was discovered by American astronomer Jeff T. Alu at the U.S. Palomar Observatory, California, on 12 March 1988.[5]
The S-type asteroid orbits the Sun at a distance of 0.6–1.9 AU once every 17 months (523 days). Its orbit has a high eccentricity of 0.50 and an inclination of 3° with respect to the ecliptic.[1]
The asteroid has an Earth minimum orbit intersection distance (MOID) of 0.024 AU (3,600,000 km). 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 0.02437 AU (3,646,000 km) from Earth. It also makes close approaches to Mars and Venus.[1]
An ambiguous light-curve was obtained through photometric observations by Czech astronomer Petr Pravec in 1998. The light-curve gave a rotation period of 2.760±0.002 hours with a brightness amplitude of 0.20 in magnitude. The alternative period solution is 2.919±0.22 hours with an amplitude of 0.22 in magnitude (U=2).[3]
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.[3] 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.[2]
