Doloreshill

Key Facts

• Categorized as a Amor-class Asteroid
• Comparable in size to the U.S. Capitol building
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

Doloreshill is a very small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified Doloreshill 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.

Doloreshill orbits the sun every 1,120 days (3.07 years), coming as close as 1.28 AU and reaching as far as 2.95 AU from the sun. Based on its brightness and the way it reflects light, Doloreshill is probably between 0.265 to 0.592 kilometers in diameter, making it larger than 90% of asteroids but tiny compared to large asteroids, very roughly comparable in size to the U.S. Capitol building.

No Close Approaches

Doloreshill's orbit is 0.28 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

Doloreshill's orbit is determined by observations dating back to Oct. 20, 2001. It was last officially observed on May 20, 2010. The IAU Minor Planet Center records 208 observations used to determine its orbit.

Accessibility and Exploration

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