Overview

26310 (1998 TX6) is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1998 TX6 as a "Near Earth Asteroid" due to its orbit's proximity to Earth, but it is not considered potentially hazardous because computer simulations have not indicated any imminent likelihood of future collision.

1998 TX6 orbits the sun every 1,140 days (3.12 years), coming as close as 1.14 AU and reaching as far as 3.14 AU from the sun. Based on its brightness and the way it reflects light, 1998 TX6 is probably between 0.359 to 0.802 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

1998 TX6's orbit is 0.16 AU from Earth's orbit at its closest point. This means that there is a wide berth between this asteroid and Earth at all times.

1998 TX6 has 4 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
July 26, 2048 25,112,537 5.060
Aug. 12, 2073 26,226,970 5.881
July 26, 2145 27,077,136 5.614
Aug. 10, 2170 23,005,129 4.907

Images and Observations

1998 TX6's orbit is determined by observations dating back to July 8, 1951. It was last officially observed on July 30, 2023. The IAU Minor Planet Center records 189 observations used to determine its orbit.

Accessibility and Exploration

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