A comet is coming close to Earth on April 1st, and that's no joke. Astronomers say the comet will make its closest fly-by of Earth since it was discovered in 1858.
However, "closest" doesn't mean close. The comet will be more than 13-million miles from Earth when it sails past.
EarthSky.org says amateur astronomers with small telescopes can get a good look. The best time to look will be around 9 p.m. Eastern Time on Saturday.
That's when the comet should be near the handle of the Big Dipper in the northern sky.
