  • See orbit simulation

Overview

2000 SG344 is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2000 SG344 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

2000 SG344 orbits the sun every 353 days (0.97 years), coming as close as 0.91 AU and reaching as far as 1.04 AU from the sun. Based on its brightness and the way it reflects light, 2000 SG344 is probably between 0.020 to 0.089 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2000 SG344's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is very close to Earth's orbit.

2000 SG344 has 7 close approaches predicted in the coming decades:
