2008 GB4

Key Facts

• Categorized as a Apollo-class Asteroid
• Comparable in size to a school bus or smaller
• Will pass within 7,437,444 km of Earth in 2097
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

2008 GB4 is a very small asteroid whose orbit crosses the orbit of Earth. NASA JPL has classified 2008 GB4 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.

2008 GB4 orbits the sun every 591 days (1.62 years), coming as close as 1.00 AU and reaching as far as 1.75 AU from the sun. Based on its brightness and the way it reflects light, 2008 GB4 is probably between 0.061 to 0.136 kilometers in diameter, making it a small to average asteroid, very roughly comparable in size to a school bus or smaller.

Close Approaches

2008 GB4'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.

2008 GB4 has 1 close approaches predicted in the coming decades:
