2017 HT3 is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2017 HT3 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.
2017 HT3 orbits the sun every 733 days (2.01 years), coming as close as 1.15 AU and reaching as far as 2.03 AU from the sun. Based on its brightness and the way it reflects light, 2017 HT3 is probably between 0.091 to 0.204 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2017 HT3's orbit is 0.14 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.
2017 HT3 has 3 close approaches predicted in the coming decades:
Date | Distance from Earth (km) | Velocity (km/s) |
---|---|---|
May 3, 2019 | 21,740,352 | 18.176 |
May 3, 2021 | 24,122,460 | 18.184 |
May 5, 2023 | 27,892,123 | 18.268 |
2017 HT3's orbit is determined by observations dating back to April 16, 2017. It was last officially observed on April 25, 2023. The IAU Minor Planet Center records 152 observations used to determine its orbit.
