Overview
2015 TE323 is a small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2015 TE323 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2015 TE323 orbits the sun every 1,190 days (3.26 years), coming as close as 0.88 AU and reaching as far as 3.52 AU from the sun. Based on its brightness and the way it reflects light, 2015 TE323 is probably between 0.574 to 1.282 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
Close Approaches
2015 TE323's orbit is 0.03 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.
2015 TE323 has 8 close approaches predicted in the coming decades:
