Below is a radar view of asteroid 2021 DA14 as it receded from the earth after its flyby on Feb.15th.

Radar observations of asteroid 2012 DA14 generated from data obtained by NASA’s Goldstone Solar System Radar on Feb. 15-16, 2013. During the observations, the space rock’s distance increased from 74,000 to 195,000 miles (120,000 to 314,000 km) from Earth.

The movie is comprised of 73 radar “images” looped nine times.
Resolution is 4 meters per pixel.

Alan Stern and naming exoplanets

Alan Stern, former head of the New Horizons mission to Pluto and former head of NASA space science division, is also involved in several commercial ventures, including Uwingu, which aims to raise money for space science projects via profit making products and services. The first Uwingu service invites the public to suggest names for the many planets that are being found orbiting other stars. The names selected will not be official or binding but the activity can still be fun for the public. Stern talks with New Scientist about  Uwingu and exoplanet naming: We need to rethink how we name exoplanets – New Scientist.
