Overview

2020 RT2 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2020 RT2 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.

2020 RT2 orbits the sun every 550 days (1.51 years), coming as close as 0.88 AU and reaching as far as 1.75 AU from the sun. Based on its brightness and the way it reflects light, 2020 RT2 is probably between 0.004 to 0.018 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2020 RT2's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2020 RT2 has 4 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
Sept. 9, 2020 472,412 9.405
Sept. 12, 2023 4,209,970 10.030
Sept. 18, 2026 16,444,705 12.402
April 23, 2091 23,576,297 13.145

Images and Observations

2020 RT2's orbit is determined by observations dating back to Sept. 10, 2020. It was last officially observed on Sept. 16, 2020. The IAU Minor Planet Center records 27 observations used to determine its orbit.

Accessibility and Exploration

2020 RT2 can be reached with a journey of 378 days. This trajectory would require a delta-v of 11.129 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 89 potential trajectories and launch windows to this asteroid.
