Wolf 1069

Wolf 1069 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 Wolf 1069 rather than just read about it. In short: Wolf 1069 is a red dwarf star located 31.2 light-years (9.6 parsecs) away from the Solar System in the constellation of Cygnus. The star has 17% the mass and 18% the radius of the Sun, a temperature of 3,158 K (2,885 °C; 5,225 °F), and a slow rotation period of 150–170 days.

Key takeaways

Wolf 1069 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Wolf 1069 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Wolf 1069 from memory before moving on to harder problems.

Reference excerpt

Wolf 1069 is a red dwarf star located 31.2 light-years (9.6 parsecs) away from the Solar System in the constellation of Cygnus. The star has 17% the mass and 18% the radius of the Sun, a temperature of 3,158 K (2,885 °C; 5,225 °F), and a slow rotation period of 150–170 days. It hosts one known exoplanet called Wolf 1069 b which could possibly sustain life.

Planetary system A planetary companion to Wolf 1069 was discovered in 2023 via radial velocity. It has a minimum mass close to that of Earth and orbits within the habitable zone of its star, with an orbital period of 15 days. This planet does not transit its host star. Observations have ruled out any additional planets greater than one Earth mass with orbital periods of less than 10 days. As of its discovery, Wolf 1069 b is the sixth-closest known Earth-mass planet within the conservatively defined habitable zone, after Proxima Centauri b, GJ 1061 d, Teegarden's Star c, and GJ 1002 b & c.

Worked examples

Example 1 — a first encounter with Wolf 1069

Start with the simplest possible case. Write down what Wolf 1069 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 Wolf 1069 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 Wolf 1069 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 Wolf 1069

In research: Wolf 1069 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 Wolf 1069 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: Wolf 1069 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cygnus (constellation), Gliese and GJ objects, M-type main-sequence stars, so understanding it makes those chapters shorter.
In everyday life: Look for Wolf 1069 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.
