477719 (2010 SG15) is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2010 SG15 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.
2010 SG15 orbits the sun every 1,100 days (3.01 years), coming as close as 1.09 AU and reaching as far as 3.07 AU from the sun. Based on its brightness and the way it reflects light, 2010 SG15 is probably between 0.024 to 0.054 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2010 SG15's orbit is 0.09 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.
2010 SG15 has 6 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|Oct. 11, 2019||13,761,777||4.877|
|Oct. 9, 2022||13,825,533||4.999|
