NASA Discovers Potentially Habitable Earth-Sized World “TOI 700 d” in Star’s ‘Goldilocks’ Zone

• The Transiting Exoplanet Survey Satellite (TESS)of the National Aeronautics and Space Administration (NASA) has discovered an Earth-sized world ‘Goldilocks’ zone within the habitable range of the star. Scientists confirmed the find as TOI 700 d by using NASA’s Spitzer Space Telescope.

About Goldilocks Zone:

• The Goldilocks Zone refers to the habitable zone around a star where the temperature is not too hot and not too cold and liquid water to exist on this planet.

Key Points:

• TESS discovered three planets in the satellite named TOI 700 b, c and d.
• First habitable-zone Earth-sized planet is TOI 700 d, the outermost planet 20% larger than Earth and orbits its star in 37 days.
• TOI 700 d is 100 light years away from earth.
• TOI b is the innermost planet which is rocky and TOI c is the middle planet between Earth and Neptune.
• TESS was launched by NASA on 18 April 2018 to find the earth-sized planet orbiting nearby stars.
