Comet Ison similarly failed to survive the Sun’s intense heat and gravity during perihelion in 2013.” Star gazers should be able to see the C/2023 A3 comet with their naked eyes on Thursday ...

Comet Tsuchinshan-ATLAS has not disappointed - and we have the pictures now to prove it. The comet, formally known as C/2023 A3, was first discovered in January 2023 by Purple Mountain Observatory ...

On Nov. 28 ISON hurtles through perihelion, its closest approach to the sun. Let’s hope this comet brightens and becomes visible to the naked eye, because so far it’s been a bit of a ...

Comet Gröller tops them all in terms of its closest approach to the Sun, or perihelion, which is the most distant of any comet yet found. This new comet, never gets closer than 14.1 AU from the Sun.

In the coming months—and years—the comet will face its two greatest challenges to survival. First, the Sun. 73P will reach Perihelion, its closest approach to the Sun, on March 16th.

The semi-axis major of Halley's comet was already known with considerable precision, from this body having been observed at several returns to perihelion since the year 1456, and in 1835 an ...

Following perihelion, the comet showed signs of disintegration but still put on a dazzling display of bright tails. As it heads toward the edge of the solar system, it will slowly start to fade.

Comet Ison, which was thought to have vaporized, seems to be alive and kicking. According to NASA on Nov. 29 (KST), the comet was spotted within the sun's orbit. Experts had thought the comet ...

Comet ISON - called by some the "comet of the century" made its way around the sun tonight, but we aren't sure if it survived the trip or not. What happened to the chunk of rock and ice determines ...

Currently shining at magnitude +8 as it glides through the umlaut-adorned constellation Boötes the Herdsman, Comet V2 Johnson is expected to top out at magnitude +6 in late June, post-perihelion.
