Overview

2004 HX53 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2004 HX53 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.

2004 HX53 orbits the sun every 476 days (1.30 years), coming as close as 0.79 AU and reaching as far as 1.59 AU from the sun. Based on its brightness and the way it reflects light, 2004 HX53 is probably between 0.033 to 0.148 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2004 HX53's orbit is 0.02 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.

2004 HX53 has 21 close approaches predicted in the coming decades:

Images and Observations

2004 HX53's orbit is determined by observations dating back to April 26, 2004. It was last officially observed on April 4, 2017. The IAU Minor Planet Center records 100 observations used to determine its orbit.

Accessibility and Exploration

2004 HX53 can be reached with a journey of 394 days. This trajectory would require a delta-v of 10.242 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 533 potential trajectories and launch windows to this asteroid.
