TOI-813 b

TOI-813 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-813 b rather than just read about it. In short: TOI-813 b is a Saturn sized exoplanet orbiting the star TOI-813, a evolved and bright subgiant G-type star located 858 light years away from Earth. The exoplanet is a Neptune like gas giant type planet with 42 M🜨 and 6.7 R🜨.

Key takeaways

TOI-813 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-813 b to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of TOI-813 b from memory before moving on to harder problems.

Reference excerpt

TOI-813 b is a Saturn sized exoplanet orbiting the star TOI-813, a evolved and bright subgiant G-type star located 858 light years away from Earth. The exoplanet is a Neptune like gas giant type planet with 42 M🜨 and 6.7 R🜨. In approximately 780 million years, the planet will be engulfed and destroyed by its parent star. TOI-813 b was discovered as part of the Planet Hunters project.

Orbit The planet orbits the star TOI-813 at 0.423 AU and an orbital eccentricity of 0.05. TOI-813 b has an orbital inclination of 89.64.

Worked examples

Example 1 — a first encounter with TOI-813 b

Start with the simplest possible case. Write down what TOI-813 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-813 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-813 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-813 b

In research: TOI-813 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-813 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-813 b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanets discovered by Planet Hunters, Exoplanets discovered by TESS, Exoplanets discovered in 2019, so understanding it makes those chapters shorter.
In everyday life: Look for TOI-813 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.
