Overview

2021 LT8 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2021 LT8 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.

2021 LT8 orbits the sun every 1,150 days (3.15 years), coming as close as 1.14 AU and reaching as far as 3.15 AU from the sun. Based on its brightness and the way it reflects light, 2021 LT8 is probably between 0.046 to 0.103 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2021 LT8's orbit is 0.13 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.

2021 LT8 has 1 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
July 24, 2021 22,707,180 6.456

Images and Observations

2021 LT8's orbit is determined by observations dating back to June 14, 2021. It was last officially observed on July 8, 2021. The IAU Minor Planet Center records 29 observations used to determine its orbit.
