On April 29, 2020, a large asteroid is expected to fly by earth at a distance of approximately 4 million miles. That may be of interest to stargazers, but the previous sentence isn’t very alarming or attention-grabbing. Yet many media outlets wrote headlines about this incoming asteroid as if it posed an immediate and catastrophic threat to the planet. Asteroid 52768 (1998 OR2) was first discovered (as its name implies) in 1998, so this asteroid isn’t making a sudden and scary appearance above Earth. NASA has been monitoring it for more than two decades and has learned quite a bit. For instance, the asteroid is relatively large with a diameter between 1.1 and 2.5 miles, and it will be traveling at just under 20,000 mph when it makes its closest approach to Earth.
