2003 YD45

Key Facts

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

Overview

2003 YD45 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2003 YD45 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.

2003 YD45 orbits the sun every 1,440 days (3.94 years), coming as close as 0.77 AU and reaching as far as 4.22 AU from the sun. Based on its brightness and the way it reflects light, 2003 YD45 is probably between 0.168 to 0.375 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a football field.

No Close Approaches

2003 YD45's orbit is 0.03 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

2003 YD45's orbit is determined by observations dating back to Dec. 20, 2003. It was last officially observed on Jan. 19, 2004. The IAU Minor Planet Center records 60 observations used to determine its orbit.

Accessibility and Exploration

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