143527 (2003 EN16)

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

143527 (2003 EN16) is a small asteroid whose orbit approaches the orbit of Earth but does not cross it. NASA JPL has classified 2003 EN16 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.

2003 EN16 orbits the sun every 782 days (2.14 years), coming as close as 1.08 AU and reaching as far as 2.25 AU from the sun. Based on its brightness and the way it reflects light, 2003 EN16 is probably between 0.493 to 1.102 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.

No Close Approaches

2003 EN16's orbit is 0.19 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 EN16's orbit is determined by observations dating back to March 8, 2003. It was last officially observed on Nov. 16, 2021. The IAU Minor Planet Center records 457 observations used to determine its orbit.

Accessibility and Exploration

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