The TOI-1752 planetary system, located approximately 337 light-years from Earth, has been confirmed to contain two planets. 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. The discovery was led by the Instituto de Astrofísica de Andalucía (IAA-CSIC) with contributions from the Instituto de Astrofísica de Canarias (IAC). Observations were made using instruments including MuSCAT2 at the Teide Observatory, alongside data from NASA's TESS satellite and other telescopes. These combined observations helped confirm that the detected signals corresponded to two planets rather than other astronomical phenomena. The findings were published in the scientific journal Monthly Notices of the Royal Astronomical Society (MNRAS). ## Disagreement on planet size While most reports agree on the existence and general characteristics of the two planets, one outlet provided a specific size comparison for TOI-1752 c. La Voz de Galicia, El Correo, and SUR in English state that TOI-1752 c is twice the size of Earth. Other reports do not specify the size of this planet. ## What the coverage left out None of the left-rated digests mention the specific temperature estimate of 20 degrees Celsius for TOI-1752 c, which was present in the full report from Eldiario.es and in some centre and right-rated digests. The left-rated digests also do not mention the specific size comparison of TOI-1752 c being twice the size of Earth, a detail present in some centre and right-rated reports. ## Who covered it Shares of the 10 covering outlets with a published leaning rating: - Left: 20% (2) - Centre: 40% (4) - Right: 40% (4) 6 of 16 covering outlets carried no usable leaning rating and were excluded from those percentages. Coverage measured 2026-08-31T21:23:24.752Z. **Coverage watch:** developing. Checked 8 times; 0 checks found a material change. Most recently checked 2026-08-31T23:45:08.508Z. ## How the sides framed it ### Left - The left-rated reports from Eldiario.es and Infobae highlighted the contrasting nature of the two planets, describing one as a potential "lava world" and the other as being in the habitable zone. Both reports mentioned the distance of 337 light-years from Earth and the potential for liquid water on TOI-1752 c. Eldiario.es, which provided a full report, detailed the participation of the Instituto de Astrofísica de Canarias (IAC) and the use of specific instruments like MuSCAT2. It also quoted an IAC researcher, Samuel Geraldía, on the significance of the planet for understanding planetary formation and evolution. Infobae's digest focused on the confirmation of the system and the presence of a habitable world and a lava world. ### Centre - The centre-rated reports from La Voz de Galicia, 20minutos, El Correo, and europapress.es focused on the confirmation of the new planetary system and the distinct characteristics of its two planets. They consistently mentioned the presence of a potentially habitable planet and a "lava world". Several of these reports, including La Voz de Galicia and El Correo, stated that TOI-1752 c is twice the size of Earth and has an estimated temperature of around 18 degrees Celsius, suggesting it could hold liquid water and an atmosphere. The role of Spanish astronomers and institutes like IAA-CSIC was also noted. ### Right - The right-rated reports from SUR in English, Libertad Digital, El Mundo, and La Razón highlighted the discovery of a planetary system with both a habitable planet and a "world of lava". They consistently mentioned the distance of 337 light-years from Earth. SUR in English and La Voz de Galicia (centre) noted that TOI-1752 c is twice the size of Earth and has a temperature of around 18C. Libertad Digital and La Razón focused on the finding of a planet in the habitable zone and a lava world. El Mundo's digest mentioned the confirmation of two exoplanets from the Teide Observatory, one with extreme temperatures and the other potentially capable of supporting life. ## Factuality profile of the covering outlets These are published factuality ratings of the outlets, not a verdict on whether this story or its claims are true. - mixed: 1 - high: 4 - unknown: 8 - veryHigh: 3 ## Verification scope This page compares coverage and scores the source reporting.
