Due to the massive size of its nucleus, Comet Hale–Bopp was observed intensively by astronomers during its perihelion passage, and several important advances in cometary science resulted from these observations. The dust production rate of the comet was very high (up to 2.0 × 10 6 kg/s), [43] which may have made the inner coma optically ...
Halley's Comet is the only known short-period comet that is consistently visible to the naked ... Despite the vast size of its coma, Halley's nucleus is relatively ...

The comet is massive in size and length. Its head currently measures a whopping two miles in diameter. The tail, which is largely comprised of tiny pieces of ice and dust, is believed to be as ...
12P/Pons–Brooks is a periodic comet with an orbital period of 71 years. [9] Comets with an orbital period of 20–200 years are referred to as Halley-type comets.It is one of the brightest known periodic comets, reaching an absolute visual magnitude of about 5 in its approach to perihelion. [2]
During a flyby in September 2001, the Deep Space 1 spacecraft observed the nucleus of Comet Borrelly and found it to be about half the size (8×4×4 km) [50] of the nucleus of Halley's Comet. [48] Borrelly's nucleus was also potato-shaped and had a dark black surface. [ 48 ]
The size of the comet. This comet is an “average size comet,” Eakes said, “but it is making a relatively close pass to our inner solar system” — which makes it more visible. How close ...
