333889 (1998 SV4)

Key Facts

• Categorized as a Aten-class Asteroid
• Comparable in size to the Golden Gate Bridge (0.92 km diameter)
• Classified as a Near Earth Asteroid (NEA)
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

333889 (1998 SV4) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 1998 SV4 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.

1998 SV4 orbits the sun every 269 days (0.74 years), coming as close as 0.29 AU and reaching as far as 1.34 AU from the sun. 1998 SV4 is about 0.9 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.

The rotation of 1998 SV4 has been observed. It completes a rotation on its axis every 2.82 hours.

No Close Approaches

1998 SV4's orbit is 0.34 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

1998 SV4's orbit is determined by observations dating back to Sept. 19, 1998. It was last officially observed on Oct. 15, 2021. The IAU Minor Planet Center records 848 observations used to determine its orbit.

Accessibility and Exploration

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