HD 153072

HD 153072 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 HD 153072 rather than just read about it. In short: HD 153072, also named Shengong, is a binary star system in the constellation Scorpius, about 326 light-years (100 parsecs) distant. With an apparent magnitude of 6.05, it is very faintly visible to the naked eye under ideal viewing conditions.

Key takeaways

HD 153072 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect HD 153072 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HD 153072 from memory before moving on to harder problems.

Reference excerpt

HD 153072, also named Shengong, is a binary star system in the constellation Scorpius, about 326 light-years (100 parsecs) distant. With an apparent magnitude of 6.05, it is very faintly visible to the naked eye under ideal viewing conditions. Both components are A-type stars; sources differ as to the luminosity class, some listing it as a main-sequence star and others as a giant star. The two stars orbit with a period of 38.7 years and a low eccentricity. In Chinese astronomy, Shéngōng (simplified Chinese: 神宫; traditional Chinese: 神宮, "Divine Palace") is a single-star asterism associated with the lunar mansion Wěi (Tail). It has variously been identified as the star μ2 Scorpii (Pipirima); the star cluster NGC 6231; or another faint star or patch of stars near μ2, embedded in clouds of the Milky Way. In the latter case, the position in old star catalogues most closely corresponds to this star, HIP 83100. The IAU Working Group on Star Names approved the name Shengong for the primary component HD 153072 A on 16 October 2025 and it is now so entered in the IAU Catalog of Star Names.

Worked examples

Example 1 — a first encounter with HD 153072

Start with the simplest possible case. Write down what HD 153072 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 HD 153072 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 HD 153072 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 HD 153072

In research: HD 153072 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 HD 153072 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: HD 153072 is common in secondary-school and first-year university syllabi. It links to neighbouring topics A-type stars, Binary stars, Bright Star Catalogue objects, so understanding it makes those chapters shorter.
In everyday life: Look for HD 153072 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.
