Even at its minimum estimated diameter, C/2014 UN 271 is the largest Oort cloud comet discovered, being more than 50 times larger than a typical comet which is less than 2 km (1.2 mi) in diameter. The previous largest known long-period comet was C/2002 VQ 94 (LINEAR) with a diameter of 96 km (60 mi), [35] followed by Comet Hale–Bopp at 74 km ...
The comet was discovered in the constellation of Equuleus by Father Nicolas Sarabat, a professor of mathematics, at Nîmes in the early morning of August 1, 1729. [7] At the time of discovery the comet was making its closest approach to Earth at a distance of 3.1 AU (460 million km; 290 million mi) and had a solar elongation of 155 degrees.
It is estimated to be between 60 and 230 miles wide, which could make it the largest comet ever discovered, EarthSky said. To put the size in context, Halley's Comet is about 3.5 miles wide, Long ...
The space agency said it’s the biggest comet nucleus ever recorded with an estimated diameter of 80 miles and overall bigger than the state of Rhode Island. NASA spots ‘record-breaking ...
The Great Comet of 390 AD, also known as C/390 Q1 by its modern designation, was a comet that appeared very bright in the night sky. It was recorded prominently in ancient Chinese and Korean texts, particularly the Chén Shū .
The largest asteroid, Ceres, is only about 600 miles wide. As space objects go, comets and meteors are not very big. The largest asteroid, Ceres, is only about 600 miles wide.
The second comet found to have a periodic orbit was Encke's Comet (with the official designation of 2P/Encke). During the period 1819–1821 the German mathematician and physicist Johann Franz Encke computed the orbits for a series of comets that had been observed in 1786, 1795, 1805, and 1818, and he concluded that they were the same comet ...
Named Comet Bernardinelli-Bernstein, it was perhaps the largest comet ever detected, likely some 10 times larger than the 6-mile-wide object that pummeled Earth and triggered the dinosaurs ...
