Key Facts

Overview

1994 TA is a large asteroid with an orbit between Jupiter and Neptune. NASA JPL has not classified 1994 TA as potentially hazardous because its orbit does not bring it close to Earth.

1994 TA orbits the sun every 25,000 days (68.45 years), coming as close as 11.70 AU and reaching as far as 21.80 AU from the sun. Based on its brightness and the way it reflects light, 1994 TA is probably between 13.322 to 29.788 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the city of Philadelphia.

No Close Approaches

1994 TA's orbit is 10.70 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

1994 TA's orbit is determined by observations dating back to Oct. 4, 1994. It was last officially observed on Oct. 19, 1998. The IAU Minor Planet Center records 19 observations used to determine its orbit.

Accessibility and Exploration

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