2018 PY7

Key Facts

• Categorized as a Apollo-class Asteroid
• Comparable in size to a school bus or smaller
• Will pass within 3,400,009 km of Earth in 2020
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

2018 PY7 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2018 PY7 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.

2018 PY7 orbits the sun every 726 days (1.99 years), coming as close as 0.96 AU and reaching as far as 2.20 AU from the sun. Based on its brightness and the way it reflects light, 2018 PY7 is probably between 0.012 to 0.026 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2018 PY7's orbit is 0.00 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

2018 PY7 has 9 close approaches predicted in the coming decades:
