Many astronomers of his time believed that Earth was the center of the solar system, but Nicolaus Copernicus who died about 20 years before Shakespeare's birth published findings showing that the center was actually the sun. He has also offered dozens of conferences related to asteroids and comets at the Arecibo Observatory. Thus, 2022 E3 (ZTF). Sign up for CNNs Wonder Theory science newsletter.

Largest known comet is heading close enough to us to become visible When Halley next returns to Earth's vicinity, one astronomer predicted it could be as bright as apparent magnitude -0.3. Comets reflect different colors of light due to their current positions in orbit and chemical compositions. Updated At a distance of about 170million miles from Earth, Jewittwarned stargazers thatthe K2 comet will still be quite far away.
