2017 MW4 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2017 MW4 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 MW4 orbits the sun every 464 days (1.27 years), coming as close as 0.91 AU and reaching as far as 1.44 AU from the sun. Based on its brightness and the way it reflects light, 2017 MW4 is probably between 0.254 to 0.568 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to a football field.
2017 MW4's orbit is 0.05 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.
