Key Facts

Overview

Tacescu is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Tacescu as potentially hazardous because its orbit does not bring it close to Earth.

Tacescu orbits the sun every 1,410 days (3.86 years), coming as close as 2.20 AU and reaching as far as 2.71 AU from the sun. Tacescu is about 2.9 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to Mount Everest.

No Close Approaches

Tacescu's orbit is 1.19 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

Tacescu's orbit is determined by observations dating back to March 14, 1991. It was last officially observed on June 23, 2023. The IAU Minor Planet Center records 1,894 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
