2017 YH is a small asteroid with an orbit that is entirely confined within Earth's orbit. NASA JPL has classified 2017 YH 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 YH orbits the sun every 185 days (0.51 years), coming as close as 0.33 AU and reaching as far as 0.94 AU from the sun. Based on its brightness and the way it reflects light, 2017 YH is probably between 0.582 to 1.300 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, very roughly comparable in size to the Golden Gate Bridge.
2017 YH's orbit is 0.12 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 YH has 21 close approaches predicted in the coming decades:
