An eyeball planet is a hypothetical type of tidally locked planet, for which tidal locking induces spatial features (for example in the geography or composition of the planet) resembling an eyeball. They are terrestrial planets where liquids may be present, in which tidal locking will induce a spatially dependent temperature gradient (the planet will be hotter on the side facing the star and colder on the other side). This temperature gradient may therefore limit the places in which liquid may exist on the surface of the planet to ring- or disk-shaped areas.
Such planets are further divided into "hot" and "cold" types, depending on which side of the planet the liquid is present. A "hot" eyeball planet is usually closer to its host star, and the centre of the "eye", facing the star (day side), is made of rock while liquid is present on the opposite side (night side). A "cold" eyeball planet, usually farther from the star, will have liquid on the side facing the host star while the rest of its surface is made of ice and rocks.
Because most planetary bodies have a natural tendency toward becoming tidally locked to their host body for a long enough timeline, eyeball planets may be common and could host life, particularly in planetary systems orbiting red and brown dwarf stars which have lifespans much longer than other main-sequence stars.

Jul 25, 2019 · $\begingroup$ The concept of an eyeball planet is an artifact of early, 1D atmosphere simulations. Newer 3D models always show a strong permanent eastwards wind which will equalize out the temperature. Just google up some papers on tidally locked planet atmosphere circulation and you'll the why this type of planet is purely fictional. $\endgroup$
May 31, 2021 · Where on Earth climate is largely determined by distance from the equator, climate on our tidally locked planet will be determined by distance from the substellar zone, forming an arrangement that is concentric, like a target or eyeball, rather than lateral like Earth's latitudes. Bear this in mind, and place your climate regions accordingly.
Dec 2, 2014 · It would be generally assumed that the air cells on our tidally-locked planet would look like Hadley/Ferrel/Polar Air cells going from the day side to the night side. Some people think there would be areas of permanent rain where hot/cold air meet, and that there would at least be a ring of habitability somewhere around there.
Jan 7, 2024 · The planet still has an axis of rotation, and it has a north pole and a south pole. The difference from a not-tidally locked planet is that the tidal lock provides for a natural prime meridian. For example, see the coordinate system used for our tidally locked Moon. North pole: The pole around which the planet rotates counterclockwise.
Apr 18, 2020 · An eyeball planet is a hypothetical type of tidally locked planet, for which tidal locking induces spatial features (for example in the geography or composition of the planet) resembling an eyeball.1 It is mainly used for terrestrial planets where liquids may be present, in which tidal locking will induce a spatially dependent temperature ...
May 6, 2024 · $\begingroup$ Yes, in spades, really big spades too .. "I’m not hugely concerned with the feasibility" Oh it's feasible all right, called Tidal locking, it gives you an Eyeball planet and the weather is going to be awful, like really awful, arctic on the night side blistering desert on the day side and constant strong winds across the surface from the night side to the days side .. …
How can humans (like that that are on Earth now) stop planet from rotating (tidaly lock it, to make an eyeball planet)? Is that technologicaly possible? Can moons of that planet help them? They wan...
At any point on the habitable twilight-zone the sun would therefore be stationary somewhere near the horizon. The eyes might also be slightly different in the twilight-zone slightly nearer the sun-facing side than closer to the shadow-side of the planet, the sun being slightly higher in the sky or right on the horizon, respectively.
Aug 4, 2021 · It shows how such a planet is gonna look like. Mercury is such a planet (like our moon with us, tidally locked with the Sun). Im not asking if life is possible in a tidally locked planet. The mechanism for the dimished rotation is different and it's pretty clear to me that life on such a planet is difficult, if not impossible. When nothing is done.
I recently attended a talk on current research into exoplanets and it got me thinking. I want to create a setting on a tidally locked eyeball planet for a futuristic sci-fi story. What I want to...
