Naming the Planets

Name the planets in our solar system in order from the Sun and use vocabulary for space — planet, star, sun, moon, satellite, orbit, solar system, galaxy, universe, asteroid, comet — applying these correctly when describing the structure of the solar system and objects we see in the sky

Quick check

Can the learner name the planets in order from the Sun — and explain the difference between a star, a planet, and a moon?

Ask this to see whether the topic is secure.

Topic // Mastery

What mastery looks like

What a learner can do once this topic is secure.
  • Name the eight planets in order from the Sun without prompting
  • Use 'orbit' correctly to describe the movement of planets around the Sun and moons around planets
  • Distinguish between a planet, a moon, a star, and an asteroid using the correct vocabulary

The approach

A space-vocabulary/naming topic for ages 5–8: learn the eight planets in order from the Sun and the core space nouns (planet, star, sun, moon, satellite, orbit, solar system, galaxy, universe, asteroid, comet), and use them correctly to describe what is in the sky. Anchor each word to a canonical image plus one defining feature, lock in planet order with a mnemonic and ordering practice, build the load-bearing verb 'orbit' (what goes round what), and explicitly separate confusable categories — the Sun is a star (not a planet), the Moon is a satellite (not a planet), stars make their own light while planets shine by reflected light. Keep the focus on naming and correct use; defer mechanisms (why things orbit, phases) to later topics.

Common misconceptions

  • The Sun is a planet (it is a star) — or, conversely, the Sun is not a star at all.
  • The Moon is a planet, rather than a satellite orbiting Earth.
  • Stars and planets are the same, and a 'shooting star' (a meteor) is a star.
  • Pluto is still the ninth planet — it was reclassified as a dwarf planet in 2006.
  • Planets are all similar in size and packed close together, a scale error picked up from diagrams.

Useful representations

  • An ordered row of the eight planets out from the Sun, with the Sun labelled as a star.
  • A nested-orbit picture: Moon → Earth, planets → Sun, solar system within a galaxy within the universe.
  • Word–picture cards pairing each vocabulary term with an image and one distinguishing feature.
  • A mnemonic strip for planet order.

Teaching practices

  • Anchor each term to a canonical image plus one defining feature — a star makes its own light; a planet orbits a star and shines by reflected light; a moon orbits a planet; a comet trails a tail.
  • Teach planet order with a mnemonic (e.g. 'My Very Easy Method Just Speeds Up Naming') and repeated ordering practice, since naming the eight in order is the headline evidence.
  • Build the nested 'orbit' idea early — moons orbit planets, planets orbit the Sun (a star), the solar system sits within a galaxy — because 'orbit' is the word every later Earth-and-space topic depends on.
  • Explicitly separate confusable categories: the Sun IS a star, the Moon is NOT a planet, a 'shooting star' is not a star, and asteroids are small/irregular not planets.
  • Flag that pictures are not to scale (planets are not really crammed together or the same size) so the vocabulary does not smuggle in a scale misconception.
  • Keep the focus on naming and correct use at this age — defer mechanisms (why things orbit, phases) to later topics.

Activities to try

  1. 1

    Tap-through solar-system scene with category badges

    Why it works: Each space word belongs to a specific kind of object, and the key distinction the whole vocabulary hinges on — a star makes its own light, a planet shines by reflected light — is made clear through the tap-reveal comparison of two look-alike dots; it is not something a child can simply judge by eye.

    1. Explore a single richly labelled solar-system scene where tapping each body reveals its name, one memorable feature, and a category badge: planet / star / moon / asteroid / comet.
    2. Tap the Sun to lift a flap that declares 'I'm a star, not a planet'.
    3. Use a lift-the-flap that contrasts how a moon differs from a planet (a moon — also called a natural satellite — orbits a planet; a planet orbits the Sun).
    4. Tap a comet to reveal its name and its defining feature — an icy body that grows a glowing tail when it comes near the Sun — so every target word has a picture-and-feature anchor.
    5. Follow a zoom-out drill-down that travels outward: solar system → Milky Way galaxy → universe, so the nesting words land as places you move out through.
  2. 2

    Order the planets and sort sky objects

    Why it works: Naming the eight planets in order and placing each sky object in the right category are the two headline skills, rehearsed through active placement with feedback.

    1. Drag the eight planets into correct order outward from the Sun (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune), using a mnemonic such as 'My Very Easy Method Just Speeds Up Naming' as a memory aid.
    2. Sort a set of sky objects into bins by category: makes its own light (star), a big, round world that orbits the Sun and shines by borrowed light (planet), orbits a planet (moon), a small rocky body that orbits the Sun, often lumpy in shape (asteroid).
    3. Repeat the ordering until the sequence is secure.
  3. 3

    Build the nested 'orbit' idea with hands and narration

    Why it works: 'Orbit' means travelling around, not being near or next to — and the going-around relationships are nested (moon→planet, planet→Sun).

    1. Show 'orbit' with a hand — move one fist around another and say what is going around what.
    2. Narrate the nesting: the Moon orbits the Earth; the planets orbit the Sun (a star); the solar system sits within a galaxy, within the universe.
    3. Answer probe questions: 'Is the Sun a planet, or something else?'; 'What does the Moon orbit — the Earth or the Sun?' (it orbits the Earth, and travels around the Sun together with the Earth); 'If I said Mars is a moon, would that be right? Why not?'
