16 oct. 2023The tail reflects the sunlight and swoops behind the comet as it moves, giving the comet’s tail a curve. The closer a comet gets to the Sun, the longer and brighter its tail will grow.

Comet tail – Wikipedia
Parallax viewing from the Earth may sometimes mean the tails appear to point in opposite directions. [5] Size While the solid nucleus of comets is generally less than 30 km across, the coma may be larger than the Sun, and ion tails have been observed to extend 3.8 astronomical units (570 Gm; 350 × 106 mi ).

Understanding the Tails of Comet ZTF (C/2022 E3)
1 févr. 2023Comet ZTF exhibits both a dust tail (pointing upward) and a fainter antitail extending in the opposite direction. Dario Giannobile With the Moon approaching full phase, this is a good time to check in on the comet of the hour, Comet ZTF (C/2022 E3).

Comets: Facts – NASA Science
Comets actually have two tails―a dust tail and an ion (gas) tail. Most comets travel a safe distance from the Sun―comet Halley comes no closer than 89 million kilometers (55 million miles). However, some comets, called sungrazers, crash straight into the Sun or get so close that they break up and evaporate. Exploration of

Cometary Gas Tail | COSMOS – Swinburne
Alternatively known as the ‘ion tail’ or ‘plasma tail’, the gas tail of a comet generally starts to form somewhere around the orbit of Mars. Here, the Sun begins to heat the nucleus of the comet releasing gas and dust into a temporary atmosphere called the coma.

About Comets – Lunar and Planetary Institute (LPI)
Material from the coma gets swept into the tail. As comets move close to the Sun, they develop tails of dust and ionized gas. Comets have two main tails, a dust tail and a plasma tail. The dust tail appears whitish-yellow because it is made up of tiny particles — about the size of particles of smoke — that reflect sunlight. Dust are …
