2010 DG77

Key Facts

• Categorized as a Apollo-class Asteroid
• Comparable in size to a football field (0.32 km diameter)
• Classified as a Near Earth Asteroid (NEA)
• Classified as a Potentially Hazardous Asteroid (PHA)
• See orbit simulation

Overview

2010 DG77 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2010 DG77 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2010 DG77 orbits the sun every 13,500 days (36.96 years), coming as close as 0.95 AU and reaching as far as 21.23 AU from the sun. Its orbit is highly elliptical. 2010 DG77 is about 0.3 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, comparable in size to a football field.

No Close Approaches

2010 DG77's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.

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

Images and Observations

2010 DG77's orbit is determined by observations dating back to Feb. 19, 2010. It was last officially observed on Feb. 20, 2010. The IAU Minor Planet Center records 13 observations used to determine its orbit.

Accessibility and Exploration

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