Key Facts

Overview

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

Taiwan orbits the sun every 1,700 days (4.65 years), coming as close as 2.65 AU and reaching as far as 2.93 AU from the sun. Taiwan is about 19.3 kilometers in diameter, making it larger than 99% of asteroids, comparable in size to the city of Denver.

The rotation of Taiwan has been observed. It completes a rotation on its axis every 7.25 hours.

Taiwan's spectral type None (Tholen) / C (SMASSII) indicates that it is likely to contain water, iron, nickel, cobalt, nitrogen, and ammonia.

No Close Approaches

Taiwan's orbit is 1.66 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

Taiwan's orbit is determined by observations dating back to Feb. 23, 1938. It was last officially observed on June 14, 2023. The IAU Minor Planet Center records 3,831 observations used to determine its orbit.

Accessibility and Exploration

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