NASA Study Finds Near-Earth Asteroid Is Actually Comet
5 min readPreparations for Next Moonwalk Simulations Underway (and Underwater) This artist’s concept depicts a near-Earth asteroid with an elongated orbit. A few objects such as these can exhibit significant perturbations in their motion around the Sun and, like the asteroid 1998 SH2, could turn out to be regular comets with a weak tail and coma (the gas and dust around a comet’s nucleus).NASA/JPL-Caltech New research led by scientists at NASA’s Jet Propulsion Laboratory in Southern California h
