Key Facts

Overview

120348 (2004 TY364) is a dwarf planet whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2004 TY364 as potentially hazardous because its orbit does not bring it close to Earth.

2004 TY364 orbits the sun every 89,400 days (244.76 years), coming as close as 36.59 AU and reaching as far as 41.69 AU from the sun. Based on its brightness and the way it reflects light, 2004 TY364 is probably between 356.907 to 798.068 kilometers in diameter, making it one of the largest objects, very roughly comparable in size to Great Britain.

The rotation of 2004 TY364 has been observed. It completes a rotation on its axis every 11.70 hours.

No Close Approaches

2004 TY364's orbit is 35.60 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

2004 TY364's orbit is determined by observations dating back to July 16, 1983. It was last officially observed on Jan. 14, 2023. The IAU Minor Planet Center records 413 observations used to determine its orbit.

Accessibility and Exploration

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