The Sun, the planets and the moons the piece draws, lit only by sunlight.
- The SunThe Sun is an ordinary yellow dwarf star, fusing hydrogen into helium in its core, and the source of almost all the light and heat in the Solar System.
- MercuryMercury is the smallest planet and the closest to the Sun, an airless, cratered world of iron and rock that swings between scorching days and freezing nights.
- VenusVenus is the planet closest to Earth in size, smothered in a crushing carbon dioxide atmosphere and acid clouds that make its surface the hottest of any planet.
- EarthEarth is our home planet and the only world known to carry life, an ocean planet with a breathable atmosphere, moving continents and a magnetic shield.
- MarsMars is the red planet, a cold desert world with a thin atmosphere, the largest volcano in the Solar System and clear signs that water once flowed on its surface.
- JupiterJupiter is the largest planet, a gas giant more massive than all the other planets put together, striped with cloud bands and marked by the Great Red Spot.
- SaturnSaturn is the ringed planet, a gas giant less dense than water, circled by a vast, paper-thin system of rings made mostly of water ice.
- UranusUranus is an ice giant that orbits the Sun tipped on its side, a pale blue-green world found by telescope rather than known since antiquity.
- NeptuneNeptune is the outermost planet, a deep blue ice giant with the fastest winds in the Solar System, found where mathematics predicted it should be.
- PlutoPluto is a dwarf planet of the Kuiper belt, a small icy world with a nitrogen glacier shaped like a heart, a hazy atmosphere and an unusually large moon, Charon.
- MoonThe Moon is Earth’s only natural satellite, a dry, cratered world that always turns the same face to us and the only place beyond Earth that people have walked.
- PhobosPhobos is the larger and inner moon of Mars, a dark, lumpy body that circles faster than Mars spins and is slowly spiralling down towards the planet.
- IoIo is the innermost large moon of Jupiter and the most volcanically active world known, its surface painted yellow, orange and white by sulphur.
- EuropaEuropa is the icy moon of Jupiter with a global ocean of salty liquid water beneath its cracked crust, one of the most promising places to search for life.
- GanymedeGanymede is the largest moon in the Solar System, bigger than the planet Mercury, and the only moon known to generate its own magnetic field.
- CallistoCallisto is the outermost large moon of Jupiter, a dark, ancient world of ice and rock whose surface is among the most heavily cratered in the Solar System.
- TitanTitan is Saturn’s largest moon and the only moon with a thick atmosphere, a world of orange haze, methane rain and lakes of liquid hydrocarbons.
- EnceladusEnceladus is a small, brilliantly white moon of Saturn that sprays jets of water from an ocean beneath its south pole, out into space and into Saturn’s rings.
- TritonTriton is Neptune’s largest moon, orbiting backwards around its planet, almost certainly a captured Kuiper belt world with active geysers of nitrogen gas.
