Overview

452302 (1995 YR1) is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 1995 YR1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

1995 YR1 orbits the sun every 809 days (2.21 years), coming as close as 0.29 AU and reaching as far as 3.10 AU from the sun. Its orbit is highly elliptical. Based on its brightness and the way it reflects light, 1995 YR1 is probably between 0.239 to 0.535 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.

The rotation of 1995 YR1 has been observed. It completes a rotation on its axis every 5.01 hours.

Close Approaches

1995 YR1's orbit is 0.01 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.

1995 YR1 has 13 close approaches predicted in the coming decades:
