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 ...
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 ...
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 ...
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 ...
In comet nomenclature, the letter before the "/" is either "C" (a non-periodic comet), "P" (a periodic comet), "D" (a comet that has been lost or has disintegrated), "X" (a comet for which no reliable orbit could be calculated —usually historical comets), "I" for an interstellar object, or "A" for an object that was either mistakenly ...
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.
As space objects go, comets and meteors are not very big. While a planet like Earth is about 8,000 miles in diameter and a star like our Sun is about 865,000 miles across, the largest asteroid ...
C/2024 G3 (ATLAS) is a non-periodic comet, which reached perihelion on 13 January 2025, at a distance of 0.09 AU (13 million km) from the Sun. It is potentially the brightest comet of 2025, [6] with an apparent magnitude reaching −3.8 on the day of its perihelion. [5] The comet is visible in the southern hemisphere before and after perihelion.
