==== Comet-like tails ====
[[Kepler-1520b]] is a small rocky planet, very close to its star, that is evaporating and leaving a trailing tail of cloud and dust like a [[comet]].<ref>{{Cite web|last=University|first=Leiden|title=Evaporating exoplanet stirs up dust|url=https://phys.org/news/2012-08-evaporating-exoplanet.html|access-date=2022-01-17|website=phys.org|language=en}}</ref> The dust could be ash erupting from volcanos and escaping due to the small planet's low surface-gravity, or it could be from metals that are vaporized by the high temperatures of being so close to the star with the metal vapor then condensing into dust.<ref>{{Cite web|date=2012-05-18|title=New-found exoplanet is evaporating away|url=https://tgdaily.com/science/space/63469-new-found-exoplanet-is-evaporating-away/|access-date=2022-01-17|website=TGDaily|language=en-US}}</ref>

In June 2015, scientists reported that the atmosphere of [[GJ 436 b]] was evaporating, resulting in a giant cloud around the planet and, due to radiation from the host star, a long trailing tail {{convert|9|e6mi|e6km|order=flip|abbr=unit}} long.<ref name="NYT-20150625">{{cite news |last=Bhanoo |first=Sindya N. |title=A Planet with a Tail Nine Million Miles Long |url=https://www.nytimes.com/interactive/projects/cp/summer-of-science-2015/latest/exoplanet-tail |date=25 June 2015 |work=[[The New York Times]] |access-date=25 June 2015}}</ref>
