Given a paired view of a star at varying distance from the observer, the learner answers in two parts: Q1 'How does this star look — disk or point?' (correct response: 'a disk' when close, 'a point' when far) and Q2 'Why?' (correct response: 'because it is close' / 'because it is far'). The learner applies the rule across multiple stars (the Sun and Proxima Centauri) and accepts that the same body looks like a disk OR a point depending on distance.

Given an image or animation of a body in space, the learner identifies it as an outer planet when (and only when) it is a large body, made mostly of gas/ice, far from the Sun (beyond the asteroid belt).

Given an image or animation of a body in space, the learner identifies it as an asteroid when (and only when) it is a small rocky chunk in our solar system, typically (but not necessarily) found in the asteroid belt between Mars and Jupiter.

Given an image or animation of a body in space, the learner identifies it as a comet when (and only when) it is a frozen body of ice, dust, and rock that orbits the Sun (visible tail near the Sun; no tail when far from the Sun).

Given an image or animation of a body in space, the learner identifies it as a moon when (and only when) it orbits a planet, distinguishing it correctly from inner planets (1-feature minimum-difference partner), comets, asteroids, and outer planets.
