TOI-6692 b

TOI-6692 b is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand TOI-6692 b rather than just read about it. In short: TOI-6692 b is a confirmed exoplanet orbiting a G1 spectral class yellow dwarf or subgiant star, TOI-6692, at a distance of approximately 1013 light-years from the Sun. The discovery of the object was officially announced by an international team of astronomers led by Allison Bieri in late January 2026.

Reference excerpt

TOI-6692 b is a confirmed exoplanet orbiting a G1 spectral class yellow dwarf or subgiant star, TOI-6692, at a distance of approximately 1013 light-years from the Sun. The discovery of the object was officially announced by an international team of astronomers led by Allison Bieri in late January 2026. This exoplanet was detected using the transit method. The planet is a giant planet, with a mass of approximately 0.62 MJ and a radius of about 1.04 RJ. It orbits its host star at a distance of 0.512 AU, which is roughly half the distance from Earth to the Sun. One year on the planet is approximately 131 days. However, its orbit is highly eccentric, with an orbital eccentricity of 0.537. Its orbital inclination is 89.483°. The equilibrium temperature is estimated to be 467 K, or about 194 °C. Astronomers note that TOI-6692 b is one of only a few giant planets with an orbital period exceeding 100 days for which both mass and radius have been measured. Furthermore, they add that this planet is also one of the few single-transit TESS targets whose period has been definitively confirmed through subsequent photometric follow-up.

Host star The host star TOI-6692, also known as TIC 324609409, is located approximately 1013 light-years from Earth. It is either a yellow dwarf or a yellow subgiant, with a mass of about 1.05 solar masses and a radius of around 1.38 solar radii. The star's age is estimated to be 7.8 billion years, its effective temperature is 5890 K, its metallicity is -0.008 dex, and its luminosity is twice that of the Sun, at 2.08 solar luminosities. Its apparent magnitude is 11.4, making it invisible to the naked eye, or even with a small telescope.

Discovery and observation

In 2021, the TESS space telescope detected a single dip in the brightness of the star TOI-6692 in Sector 36. Since at least two transits are required for automatic planet confirmation, the signal was initially missed by algorithms. It was subsequently discovered manually by participants of the Visual Survey Group and Planet Hunters, who specialize in finding single transits. Following this, the object was assigned the status of a TESS Object of Interest (TOI). Ground-based resources were utilized to determine the mass and refine the orbital period. Regular measurements of the star's radial velocity were conducted between 2022 and 2025. The Planet Finder spectrograph on the 6.5-meter Magellan II Telescope (Las Campanas Observatory, Chile) made the primary contribution. In January 2026, an international team of researchers led by Allison Bieler published their findings in The Astrophysical Journal Letters, titled: "TOI-6692b: An eccentric 130 day period giant planet with a single transit from TESS". The analysis of the radial velocity data revealed a long-term linear drift. This indicates the presence of an additional massive body in the system on a wide orbit, whose mass and orbital period remain undetermined for now. The high eccentricity points to gravitational interaction of the planet with another object (scattering), which led to the distortion of its orbit. The planet did not migrate peacefully through the protoplanetary disk.

Worked examples

Example 1 — a first encounter with TOI-6692 b

Start with the simplest possible case. Write down what TOI-6692 b claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to TOI-6692 b before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about TOI-6692 b ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of TOI-6692 b

In research: TOI-6692 b appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses TOI-6692 b in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: TOI-6692 b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanets discovered by TESS, Exoplanets discovered in 2026, Giant planets, so understanding it makes those chapters shorter.
In everyday life: Look for TOI-6692 b outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
