16636 (1993 QP)

Key Facts

• Categorized as a Amor-class Asteroid
• Comparable in size to the Golden Gate Bridge
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

16636 (1993 QP) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 1993 QP 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.

1993 QP orbits the sun every 1,280 days (3.50 years), coming as close as 1.23 AU and reaching as far as 3.39 AU from the sun. Based on its brightness and the way it reflects light, 1993 QP is probably between 0.466 to 1.042 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.

The rotation of 1993 QP has been observed. It completes a rotation on its axis every 19.01 hours.

No Close Approaches

1993 QP's orbit is 0.24 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.

Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.

Images and Observations

1993 QP's orbit is determined by observations dating back to Aug. 23, 1993. It was last officially observed on Jan. 6, 2022. The IAU Minor Planet Center records 981 observations used to determine its orbit.

Accessibility and Exploration

This asteroid is not considered a viable target for human exploration by the NHATS study.
