Overview

2013 TQ5 is a very small asteroid with an orbit that is entirely confined within Earth's orbit. NASA JPL has classified 2013 TQ5 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.

2013 TQ5 orbits the sun every 249 days (0.68 years), coming as close as 0.65 AU and reaching as far as 0.89 AU from the sun. Based on its brightness and the way it reflects light, 2013 TQ5 is probably between 0.291 to 0.652 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to the U.S. Capitol building.

Close Approaches

2013 TQ5's orbit is 0.19 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.

2013 TQ5 has 5 close approaches predicted in the coming decades:

Date Distance from Earth (km) Velocity (km/s)
July 26, 2026 28,844,230 9.315
July 29, 2043 29,103,330 9.353
July 19, 2094 29,890,214 9.270
July 27, 2111 29,068,786 9.311
July 23, 2179 29,436,127 9.286

Images and Observations

2013 TQ5's orbit is determined by observations dating back to Oct. 2, 2013. It was last officially observed on Dec. 16, 2015. The IAU Minor Planet Center records 44 observations used to determine its orbit.
