Observations by Swift in January 2013 suggested that Comet ISON's nucleus was around 5 kilometers (3 mi) in diameter. [9] Later estimates were that the nucleus was only about 2 kilometers (1 mi) in diameter. [10] Mars Reconnaissance Orbiter (MRO) observations suggested the nucleus was smaller than 0.8 kilometers (0.5 mi) in diameter. [11]
As it reached perihelion on 12 January, it became the brightest comet since Comet Ikeya–Seki in 1965. [6] The comet was dubbed the Great Comet of 2007 by Space.com. [ 10 ] On 13 and 14 January 2007, the comet attained an estimated maximum apparent magnitude of −5.5. [ 11 ]
4P/Faye has a close approach to Jupiter every 59.3 years, which is gradually reducing its perihelion and increasing its orbital eccentricity. In the most recent close approach to Jupiter (March 2018), Faye's perihelion changed from about 1.7 AU to about 1.5 AU. [10] The comet nucleus is estimated to be about 3.5 km in diameter. [11]

At perihelion Comet Machholz passes the Sun at 122 kilometers per second (440,000 kilometers per hour). [3] It comes closer to the Sun than any numbered comet less than 321P/SOHO. [7] Between 1897 and 2102 perihelion gradually drops from 0.17 AU (25 million km) to 0.09 AU (13 million km). [14] 2081 will be the first perihelion below 0.1 AU. [14]
C/2021 A1 (Leonard) was a long period comet [4] that was discovered by G. J. Leonard at the Mount Lemmon Observatory on 3 January 2021 (a year before perihelion) when the comet was 5 AU (750 million km) from the Sun. [1] It had a retrograde orbit.
