Reference excerpt

Gaia DR3 2893941099963718528 is a blue straggler star in the constellation of Canis Major. The star is located in the open cluster NGC 2243, and is approximately 11,900 light years (3,650 parsecs) away. It has an apparent magnitude of 15.6. It was first discovered in August 2018 in the second data release of the Gaia Telescope.

Stellar characteristics Gaia DR3 2893941099963718528 is a blue straggler star in the open cluster NGC 2243. The star has an estimated radius of 1.23±0.22 R☉, and a predicted mass of 1.72±0.12 M☉. The radius was found using a bolometric luminosity of 10.59±0.03 L☉, and an effective temperature of 8,800±700 K. It is believed to be extremely metal-poor with a metallicity of −0.31±0.15 dex. It is proposed to be 510±70 million years old. The star has a spectral type of A3V. It is a fast rotating star with a rotational velocity of 95.63±9.78 km/s.

Substellar companions

In 2026, a substellar object was discovered orbiting around Gaia DR3 2893941099963718528. It is designated Gaia DR3 2893941099963718528 b and is either a planet or brown dwarf. The substellar object is in a tight, low-eccentricity compact orbit around its host star in roughly 5.6 hours. The substellar object has a mass between 20 and 70 MJ, implying that it is likely a brown dwarf. The substellar object has a radius of 0.8 RJ, and calculated temperature between 1,100 and 2,500 K.

Worked examples

Example 1 — a first encounter with Gaia DR3 2893941099963718528

Start with the simplest possible case. Write down what Gaia DR3 2893941099963718528 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 Gaia DR3 2893941099963718528 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 Gaia DR3 2893941099963718528 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 Gaia DR3 2893941099963718528

In research: Gaia DR3 2893941099963718528 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 Gaia DR3 2893941099963718528 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: Gaia DR3 2893941099963718528 is common in secondary-school and first-year university syllabi. It links to neighbouring topics A-type main-sequence stars, Astronomical objects discovered in 2018, Blue stragglers, so understanding it makes those chapters shorter.
In everyday life: Look for Gaia DR3 2893941099963718528 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.
