2017 XA1 is a very small asteroid with an orbit that is entirely confined within Earth's orbit. NASA JPL has classified 2017 XA1 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2017 XA1 orbits the sun every 266 days (0.73 years), coming as close as 0.65 AU and reaching as far as 0.97 AU from the sun. Based on its brightness and the way it reflects light, 2017 XA1 is probably between 0.153 to 0.342 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.
2017 XA1'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.
2017 XA1 has 18 close approaches predicted in the coming decades:
