TOI-1752 hosts a lava world and a sub-Neptune in the habitable zone

Star system: TOI-1752 | Distance from the Sun: 337 light years

Two exoplanets were confirmed orbiting a nearby red dwarf star TOI-1752, making it a valuable system for studying planetary diversity. The inner planet, TOI-1752 b, orbits very close to the star and is likely a lava world, with surface temperatures high enough to melt rock. The outer planet, TOI-1752 c, is a sub-Neptune-size planet that orbits within the optimistic habitable zone, where conditions could allow for liquid water.

Researchers combined data from the TESS space telescope with ground-based observations to confirm the planetary nature of both objects. They used statistical validation and machine learning to rule out false positives. TOI-1752 b is a promising target for atmospheric studies due to its high emission spectroscopy metric, while TOI-1752 c's location in the habitable zone makes it interesting for studies of potential habitability.

This system provides a unique opportunity to compare a hot, rocky planet and a cooler, potentially habitable sub-Neptune around the same star, helping scientists understand how different types of planets form and evolve.

Key findings
- TOI-1752 hosts a hot lava world and a sub-Neptune in the habitable zone
- Both planets confirmed using TESS and ground-based data
- Machine learning and statistical validation support their planetary nature
- TOI-1752 b is ideal for atmospheric studies
- TOI-1752 c is a candidate for habitability research
