Poin Utama
- IAA-CSIC scientists confirmed the TOI-1752 system, at a distance of 337 light-years.
- Two planets in the system: TOI-1752 b (lava world, <1 day orbit) and TOI-1752 c (in habitable zone, Earth-to-Neptune size).
- Discovery made using NASA's TESS satellite and the MuSCAT2 instrument at the Teide Observatory.
- TOI-1752 c could be a significant target for atmospheric studies (resembles K2-12 b).
Dalam Angka
Scientists from Spain's Andalusian Institute of Astrophysics (IAA-CSIC) confirmed the TOI-1752 planetary system, located 337 light-years away, using NASA's TESS satellite and the MuSCAT2 instrument at the Teide Observatory in Tenerife. Two planets were detected in the system: one is a 'lava world' completing its orbit in less than a day, with a surface that could feature molten rock; the other lies in the optimistic habitable zone of its red dwarf star, with a size between Earth and Neptune.
The second planet, named TOI-1752 c, holds the potential to host liquid water, though this alone does not guarantee habitability. The planet's parameters bear an almost exact resemblance to K2-12 b, one of the most studied exoplanets for atmospheric characterization, making TOI-1752 c a valuable target for future atmospheric studies.
Researchers stated that combined space and ground-based observations ruled out false positive scenarios such as a binary star or brown dwarf, confirming both objects as planets. The study was published in the journal MNRAS, adding a new candidate to the search for habitable worlds in our universe.

Pertanyaan Umum
- Where is the TOI-1752 system and how was it discovered?
- The system is 337 light-years away; it was discovered by Spanish scientists (IAA-CSIC) using NASA's TESS satellite and the MuSCAT2 instrument at the Teide Observatory in Tenerife.
- What are the characteristics of the two discovered planets?
- TOI-1752 b is a 'lava world' completing its orbit in less than a day, with possible molten rock on its surface; TOI-1752 c is a planet in the optimistic habitable zone of its red dwarf star where liquid water could exist.
- Why is this discovery important?
- TOI-1752 c closely resembles the well-studied planet K2-12 b, indicating it could be a valuable target for atmospheric characterization.
