Overview

2019 TX6 is a mid-sized asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2019 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.

2019 TX6 orbits the sun every 680 days (1.86 years), coming as close as 0.96 AU and reaching as far as 2.06 AU from the sun. Based on its brightness and the way it reflects light, 2019 TX6 is probably between 0.580 to 2.580 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to Mount Everest.

Close Approaches

2019 TX6's orbit is 0.05 AU from Earth's orbit at its closest point. This means that there is an wide berth between this asteroid and Earth at all times.

2019 TX6 has 11 close approaches predicted in the coming decades:

Images and Observations

2019 TX6's orbit is determined by observations dating back to Oct. 8, 2019. It was last officially observed on Feb. 17, 2020. The IAU Minor Planet Center records 45 observations used to determine its orbit.

Accessibility and Exploration

2019 TX6 can be reached with a journey of 362 days. This trajectory would require a delta-v of 11.892 km/s. To put this into perspective, the delta-v to launch a rocket to Low-Earth Orbit is 9.7 km/s. There are 13 potential trajectories and launch windows to this asteroid.
