Tokyogiants

Key Facts

• Categorized as a Main-belt Asteroid
• Comparable in size to the island of Manhattan
• Not a Near Earth Object
• Not a Potentially Hazardous Object
• See orbit simulation

Overview

Tokyogiants is a mid-sized asteroid orbiting between Mars and Jupiter in the main portion of the asteroid belt. NASA JPL has not classified Tokyogiants as potentially hazardous because its orbit does not bring it close to Earth.

Tokyogiants orbits the sun every 1,390 days (3.81 years), coming as close as 1.84 AU and reaching as far as 3.04 AU from the sun. Based on its brightness and the way it reflects light, Tokyogiants is probably between 3.362 to 7.517 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the island of Manhattan.

The rotation of Tokyogiants has been observed. It completes a rotation on its axis every 2.88 hours.

No Close Approaches

Tokyogiants's orbit is 0.83 AU from Earth's orbit at its closest point. This means that there is a very 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

Tokyogiants's orbit is determined by observations dating back to March 27, 1989. It was last officially observed on May 15, 2023. The IAU Minor Planet Center records 1,918 observations used to determine its orbit.

Accessibility and Exploration

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