(also 2020CD3 or CD3 for short) is a tiny near-Earth asteroid (or Claimed moons of Earth, minimoon) that ordinarily orbits the Sun but makes close approaches to the Earth–Moon system, in which it can temporarily enter Earth orbit through temporary satellite capture (TSC). It was discovered at the Mount Lemmon Observatory by astronomers Theodore Pruyne and Kacper Wierzchoś on 15 February 2020, as part of the Mount Lemmon Survey or Catalina Sky Survey. The asteroid's discovery was announced by the Minor Planet Center on 25 February 2020, after subsequent observations have confirmed that it was orbiting Earth. It is the second temporary satellite of Earth discovered ''in situ'', after , which was discovered in 2006. Based on its nominal trajectory, was captured by Earth around 2016–2017, and escaped Earth's gravitational Sphere of influence (astrodynamics), sphere of influence around 7 May 2020. will make another close pass to Earth in March 2044, though it will most likely ...
