Key Facts

Overview

27821 (1993 TU34) is a mid-sized asteroid that orbits between Mars and Jupiter in the outer reaches of the main asteroid belt. NASA JPL has not classified 1993 TU34 as potentially hazardous because its orbit does not bring it close to Earth.

1993 TU34 orbits the sun every 2,350 days (6.43 years), coming as close as 3.21 AU and reaching as far as 3.72 AU from the sun. 1993 TU34 is about 8.1 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the San Francisco Bay.

The rotation of 1993 TU34 has been observed. It completes a rotation on its axis every 3.78 hours.

No Close Approaches

1993 TU34's orbit is 2.21 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

1993 TU34's orbit is determined by observations dating back to Oct. 9, 1993. It was last officially observed on June 22, 2023. The IAU Minor Planet Center records 1,293 observations used to determine its orbit.
