TOI-715 b

TOI-715 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-715 b rather than just read about it. In short: TOI-715 b is a super-Earth exoplanet in the habitable zone of its parent M-type star, TOI-715. The planet is 1.55 times larger than Earth, and is located at 0.083 astronomical units (12,400,000 km) from its star.

Key takeaways

TOI-715 b belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect TOI-715 b to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of TOI-715 b from memory before moving on to harder problems.

Reference excerpt

TOI-715 b is a super-Earth exoplanet in the habitable zone of its parent M-type star, TOI-715. The planet is 1.55 times larger than Earth, and is located at 0.083 astronomical units (12,400,000 km) from its star. The planet orbits in the habitable zone of its star and has an equilibrium temperature of 234 K (−39 °C). It was discovered by the Transiting Exoplanet Survey Satellite (TESS) in 2023; according to the authors of the discovery paper, it is the first TESS discovery in the conservative habitable zone. NASA stated that the James Webb Space Telescope may be used in the future to look for evidence of water or planetary atmosphere. Additionally, there may be a second exoplanet in the same system, TIC 271971130.02, that, if confirmed, would be the smallest known habitable-zone exoplanet.

Conservative habitable zone The concept of "conservative habitable zone" was defined by Koparappu et al. in 2014. It is the region where the planet receives insolation equivalent to 0.42 to 0.842 times the insolation received from Earth by the Sun. As TOI-715 b has a insolation of 0.67+0.15−0.20 S🜨, it is located inside the conservative habitable zone.

TOI-715

TOI-715 is a red dwarf star located 42 parsecs (140 ly) from the Earth in the constellation Volans, very close to the southern celestial pole. The star is smaller and cooler than the Sun and has an apparent magnitude of 16.7 and is too faint to be seen with the naked eye or even a small telescope.

Worked examples

Example 1 — a first encounter with TOI-715 b

Start with the simplest possible case. Write down what TOI-715 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-715 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-715 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-715 b

In research: TOI-715 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-715 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-715 b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanets discovered by TESS, Exoplanets discovered in 2023, Super-Earths in the habitable zone, so understanding it makes those chapters shorter.
In everyday life: Look for TOI-715 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.
