Key Facts

Overview

Comet C/1937 D1 (Wilk) is an object with a medium-length orbit that is highly inclined to the ecliptic plane of the solar system. NASA JPL has classified Wilk 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.

Wilk orbits the sun every 66,000 days (180.70 years), coming as close as 0.62 AU and reaching as far as 63.32 AU from the sun. Its orbit is highly elliptical.

No Close Approaches

Wilk's orbit is 0.26 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

Wilk's orbit is determined by observations dating back to March 2, 1937. It was last officially observed on April 30, 1937. The IAU Minor Planet Center records 17 observations used to determine its orbit.

Accessibility and Exploration

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