Overview

417210 (2005 XV77) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2005 XV77 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.

2005 XV77 orbits the sun every 254 days (0.70 years), coming as close as 0.46 AU and reaching as far as 1.11 AU from the sun. Based on its brightness and the way it reflects light, 2005 XV77 is probably between 0.205 to 0.459 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

Close Approaches

2005 XV77's orbit is 0.10 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

2005 XV77 has 31 close approaches predicted in the coming decades:
