One planet, designated TOI-1752 b, orbits its star at a very close distance, completing a revolution in less than a day. Scientists suggest its surface could be molten rock due to intense radiation. The second planet, TOI-1752 c, is positioned within the optimistic habitable zone of its star. This planet is intermediate in size between Earth and Neptune and receives radiation levels comparable to Earth. Its location in the habitable zone means that, under certain atmospheric conditions, liquid water could exist on its surface. Researchers estimate its equilibrium temperature to be around 20 degrees Celsius."},{"type":"paragraph","text":"The discovery was led by the Instituto de Astrofísica de Andalucía (IAA-CSIC) with contributions from the Instituto de Astrofísica de Canarias (IAC).
