Could the ocean planet in Subnautica exist in our real universe?Explore real-life ocean planet candidates that resemble Subnautica's alien planet 4546b. From Earth-like environments to extreme conditions, this video introduces fascinating alien planets based on scientific data.
1. 🎮 Defining 4546b in Subnautica and Real-World Ocean Planets
· 4546b, the setting for the game 'Subnautica,' is a fictional ocean planet with a deep and beautiful ecosystem.
· In reality, an ocean planet or water world refers to a planet or moon where a significant portion of its hydrosphere is composed of liquid water. This could be a subsurface ocean or a surface ocean that has completely submerged the land.
· The in-game 4546b is estimated to be smaller than Earth with lower gravity and, according to the game's lore, exists in a fictional star system located in the Ariadne Arm of the galaxy.
· While about 71% of Earth's surface is covered by water, water accounts for only about 0.05% of the planet's mass. In contrast, alien ocean planets could have a much higher proportion of water, suggesting the possibility of immense water pressure and unusual ice formations.
· Currently, Earth is the only celestial body confirmed to have liquid water on its surface. However, celestial bodies within our solar system, such as Jupiter's moons Europa and Ganymede, and Saturn's moon Titan, are thought to potentially harbor significant amounts of subsurface water.

2. 🔭 Ocean Planet Candidate 1: TOI-1452 b
· TOI-1452 b is a super-Earth exoplanet with a diameter about 70% larger than Earth's and a mass five times greater.
· This planet has been proposed as a potential water world, with simulations suggesting that water could make up as much as 30% of its mass.
· It is currently located about 100 light-years from Earth and orbits a red dwarf star. Further research is planned using the James Webb Space Telescope.

3. 🪐 Ocean Planet Candidates 2 & 3: Kepler-62 f and Kepler-62 e
· Kepler-62 f has a radius about 1.4 times that of Earth and orbits within its star system's habitable zone with a period of approximately 267 days.
· This planet has potential for life due to its relatively quiet star, but the presence of an atmosphere is still uncertain. Its estimated surface temperature is around -65°C, and it might be entirely covered in ice.
· Kepler-62 e orbits just inside Kepler-62 f and is a super-Earth with a diameter 60% larger than Earth's.
· This planet could be mostly or entirely covered in water, but it lies on the boundary between rocky and gas planets, raising the possibility of it being a mini-Neptune. Additionally, it receives more stellar energy than Earth, potentially leading to a surface temperature of 77°C.

4. 🌊 Ocean Planet Candidates 4 & 5: GJ 1214 b and Kepler-22 b
· GJ 1214 b is an exoplanet with a radius about 2.7 times Earth's and a mass about 8.4 times Earth's, and it was once considered a prime candidate for a water world.
· However, recent research from the James Webb Telescope suggests it is more likely a mini-Neptune composed primarily of gas.
· Kepler-22 b was discovered about 640 light-years from Earth and is located within the habitable zone, suggesting the possibility of liquid water on its surface.
· This planet has a radius about 2.1 times that of Earth, and if it has an Earth-like greenhouse effect, its surface temperature could be around 22°C. However, with a Venus-like greenhouse effect, the temperature could soar to 460°C.

5. 🌌 The Number of Potential Ocean Planets in Our Galaxy
· Exoplanet searches tend to find larger planets closer to their stars first, making the discovery of water worlds challenging.
· However, some estimates suggest that one in five Sun-like stars may host an Earth-like planet in its habitable zone.
· This implies that there could be as many as 11 billion such planets in our Milky Way galaxy alone, offering a significant chance of discovering planets with environments similar to Subnautica.
