Pluto audio micro-course (transcript)
Podcast 1 — Introduction & meaning
Narrator: Today's word is "Pluto" — proper noun, pronounced /ˈpluːtəʊ/, with the stress on "plu".
Narrator: Pluto is a dwarf planet in the Kuiper Belt, beyond Neptune, once counted as the ninth planet of our solar system.
Narrator: In plain English, Pluto is a small, cold, distant world that astronomers no longer call a full planet.
Narrator: It is named after the Roman god of the underworld, and the name was suggested in 1930 by an eleven-year-old Oxford schoolgirl, Venetia Burney.
Narrator: "The demotion of Pluto" describes its reclassification as a dwarf planet by the International Astronomical Union in 2006.
Narrator: It differs from a planet such as Neptune because Pluto has not cleared its orbit of other icy bodies.
Narrator: "To be plutoed" is a playful figurative use, meaning to be downgraded or demoted in status.
Narrator: Astronomy, space exploration, science education and mythology all rely on the name Pluto.
Narrator: So remember: Pluto is the distant dwarf planet named after the god of the underworld, famous for losing its planetary title.

Podcast 2 — In conversation
Speaker A: I grew up learning that Pluto was a planet. Why did everyone suddenly change their minds?
Speaker B: Such a great story! PLUTO takes its name from the Roman god of the underworld, and in 2006 astronomers agreed a stricter definition of a planet, which Pluto simply didn't meet.
Speaker A: So it didn't shrink or vanish — the rules just changed around it?
Speaker B: Exactly — Pluto is still out there, now proudly classed as a dwarf planet!
Speaker A: Example sentences?
Speaker B: "The New Horizons probe flew past Pluto in 2015"; "Pluto has a heart-shaped glacier"; "poor Pluto got demoted" — a space mission, a surface feature, and a bit of affectionate humour.
Speaker A: Common mistakes?
Speaker B: Always use a capital P, because it's a proper noun; and don't call it the ninth planet today — say dwarf planet instead.
Speaker A: Close relatives?
Speaker B: "Dwarf planet" the official cousin, "Kuiper Belt object" the technical twin, "planetoid" the older alternative. Pluto keeps its distant, underdog charm!
Podcast 3 — Prompt engineering
Speaker B: Let's use "Pluto" in AI prompts — useful for astronomy learning apps and interactive quiz generators.
Speaker A: So Pluto could help an education app teach how scientific definitions change?
Speaker B: Right. For an astronomy learning app, you'd write:
Prompt: Explain to a ten-year-old in four short sentences why Pluto was reclassified as a dwarf planet in 2006.
Speaker A: How about a quiz feature?
Speaker B: Ask the model for structured questions:
Prompt: Create five multiple-choice questions about Pluto with one correct answer and three plausible distractors each, returned as JSON.
Speaker A: Could it help with a data visualisation?
Speaker B: Yes, you can request clean comparison data:
Prompt: Produce a table comparing Pluto, Eris and Ceres by diameter, distance from the Sun and number of known moons.
Speaker A: One more?
Speaker B: For a planetarium chatbot, try this:
Prompt: Act as a friendly planetarium guide and answer visitor questions about Pluto accurately, citing the New Horizons mission where relevant.
