Key Facts


434313 (2004 GP) is a very small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2004 GP 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.

2004 GP orbits the sun every 212 days (0.58 years), coming as close as 0.36 AU and reaching as far as 1.04 AU from the sun. Based on its brightness and the way it reflects light, 2004 GP is probably between 0.350 to 0.784 kilometers in diameter, making it small in absolute terms, but larger than 90% of asteroids, very roughly comparable in size to the U.S. Capitol building.

No Close Approaches

2004 GP's orbit is 0.21 AU from Earth's orbit at its closest point. This means that there is an 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

2004 GP's orbit is determined by observations dating back to April 9, 2004. It was last officially observed on May 6, 2015. The IAU Minor Planet Center records 83 observations used to determine its orbit.

Accessibility and Exploration

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