Gliese 536

Gliese 536 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 Gliese 536 rather than just read about it. In short: Gliese 536 is a red dwarf star in the constellation Virgo. It lies at a distance of approximately 34 light-years and has two known exoplanets.

Key takeaways

Gliese 536 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Gliese 536 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Gliese 536 from memory before moving on to harder problems.

Reference excerpt

Gliese 536 is a red dwarf star in the constellation Virgo. It lies at a distance of approximately 34 light-years and has two known exoplanets.

Planetary system The two known exoplanets orbiting 536 were found from Doppler spectroscopy. Gliese 536 b was discovered in 2017, while Gliese 536 c was discovered in 2025. Based on their minimum masses (m sin i) of 6.37±0.38 and 5.89±0.70 M🜨, both are thought to be either super-Earths or mini-Neptunes. The host star rotates at an angle of 58+16−19° relative to Earth, and based on the assumption that the planets share this angle, their masses would be 7.6+2.3−1.0 and 7.1+2.2−1.2 M🜨. For an inclination less than 5°, both would be gas giants. The habitable zone spans from 0.176 to 0.372 astronomical units, so planet c is orbiting just below this zone. The equilibrium temperatures of Gliese 536 b and c are 451±15 and 291±10 K.

Worked examples

Example 1 — a first encounter with Gliese 536

Start with the simplest possible case. Write down what Gliese 536 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 Gliese 536 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 Gliese 536 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 Gliese 536

In research: Gliese 536 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 Gliese 536 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: Gliese 536 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Durchmusterung objects, Henry Draper Catalogue objects, Hipparcos objects, so understanding it makes those chapters shorter.
In everyday life: Look for Gliese 536 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.
