Scientists Constantly Examine Space Telescope Data in Pursuit of Earth-Like Planets

Experts consistently examine data gathered by space telescopes, aiming to discover planets resembling Earth. One recent, intriguing find is a celestial body named TOI-733b.

TOI-733b: A New and Fascinating Discovery

Located 245 light-years away, TOI-733b boasts a radius twice the size of Earth and orbits a star slightly smaller than our Sun. According to a study published in Astronomy & Astrophysics, as well as a preprint on arXiv, the planet's density suggests it may have lost its atmosphere or could be an ocean-covered world. However, its close proximity to its parent star may eventually cause water evaporation, turning TOI-733b into a "naked rock."

Density and Composition: Comparing TOI-733b to Earth

With a density of 3.98 grams per cubic centimeter, TOI-733b's composition is less dense than Earth's 5.51 grams per cubic centimeter. Researchers, unsure of the celestial body's exact makeup, have speculated the presence of a Neptune-like atmosphere composed of hydrogen and helium. This atmosphere may have already vanished entirely. If true, the planet could have developed a secondary atmosphere containing heavier elements.

TOI-733b: Potential Ocean World with Water Vapor Atmosphere

Among the possibilities, TOI-733b might be an ocean world that, despite losing hydrogen and helium, possesses an atmosphere rich in water vapor – more resistant to photoevaporation. The scientists conclude that determining TOI-733b's precise composition holds significant implications for understanding exoplanets.
