Discussion threads can be closed at any time at our discretion. NASA plans to take advantage of the asteroid's close approach to capture radar images and learn more about Florence's surface features. He loves public outreach and has published multiple astronomy articles for EarthSky, as well as for newspapers in Puerto Rico.
Asteroid Florence Pays Earth a Visit
They start by taking four pictures of the same patch of sky, with ten minutes between each exposure, and compare them on a computer screen. Within two hours, the Minor Planet Center used sightings by others to chart its trajectory. Asteroid TC4 is 0. Mercury Globe from Astronomy magazine. They range in size from as small as a few feet to as large as 25 miles 40km for the largest NEO, Ganymed. Dawn maps Ceres craters where ice can accumulate.

Complete digital backfile to Mr Raymond suggests that Oumuamua could be one of those primordial celestial objects that are created by aggregation of grains of dust around young stars. If confirmed, accurate coordinates and, sometimes, magnitudes are submitted to the MPC. He has made asteroid discoveries, including the object recently identified as JE3 that turned out to be an Apollo 12 rocket stage.

As a reference, the distance between Earth and the moon is , miles , km.
On a good night a survey will take several hundred photos of the sky. Using these observations, professional astronomers can compute the near-Earth object's orbit and predict its future motion. Registration is free, and takes less than a minute. When the Moon is out, its glare further reduces the detectability of faint asteroids by ground based telescopes, especially near the horizon. The smaller asteroid size class, the greater the population.
