NASA’s Planetary Radar Tracks Two Large Asteroid Close Approaches

The Deep Space Network’s Goldstone planetary radar had a busy few days observing asteroids 2024 MK and 2011 UL21 as they safely passed Earth. Scientists at NASA’s Jet Propulsion Laboratory in Southern California recently tracked two asteroids as they flew by our planet. One turned out to have a little moon orbiting it, while the […]

NASA’s Planetary Radar Images Slowly Spinning Asteroid

During the close approach of 2008 OS7 with Earth on Feb. 2, the agency’s Deep Space Network planetary radar gathered the first detailed images of the stadium-size asteroid. On Feb. 2, a large asteroid safely drifted past Earth at a distance of about 1.8 million miles (2.9 million kilometers, or 7 ½ times the distance […]
