2011 HT is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2011 HT 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.
2011 HT orbits the sun every 977 days (2.67 years), coming as close as 1.06 AU and reaching as far as 2.79 AU from the sun. Based on its brightness and the way it reflects light, 2011 HT is probably between 0.111 to 0.248 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2011 HT'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.
2011 HT has 5 close approaches predicted in the coming decades:
|Date||Distance from Earth (km)||Velocity (km/s)|
|June 25, 2019||11,928,221||7.922|
|June 3, 2086||10,626,830||6.815|
|June 28, 2094||14,424,855||8.329|
|May 25, 2161||15,448,676||7.628|
|June 22, 2169||9,063,522||7.249|
2011 HT's orbit is determined by observations dating back to April 25, 2011. It was last officially observed on July 1, 2019. The IAU Minor Planet Center records 158 observations used to determine its orbit.
