Suara.com – NASA Find a Neptune-like exoplanet that is relatively close to Earth and has water clouds.
However, these observations are still very early in confirming the existence of a water cloud on the planet called TOI1231 b That.
“Future Observations New planets This will allow us to determine how ordinary water clouds form around this temperate planet,” said Jennifer Burt, a scientist at NASA’s Jet Propulsion Laboratory. outer space.com, Sunday (27/6/2021).
The data obtained are still limited, but experts confirm that TOI1231b is about 3.5 times the diameter of Earth, which is slightly smaller than Neptune. TOI1231b also has an orbital period of 24 days.

The planet orbits close to its star and TOI1231b has a relatively cool atmosphere, around 60 degrees Celsius.
When the temperature is double the Earth’s average temperature, TOI1231b is much colder than other exoplanets, typically reaching hundreds or thousands of degrees Celsius.
Experts hope to capture starlight shining through the atmosphere of TOI1231b, using transmission spectroscopy techniques from the Hubble Space Telescope or the James Webb Space Telescope (JWST) in the future.
Hubble will also look for evidence of a “tail” radiating from the planet, which would appear if hydrogen or helium atoms were seen as the planet crossed the surface of its star.
