Things in space with R

  • Real spacecraft; rockets travel through space!

  • Space rocks like asteroids and meteoroids.

  • Cosmic radiation exists throughout outer space.

  • Mars and lunar rovers explore worlds in space.

  • Planetary rings, like Saturn's, are in space.

  • Space rock: meteoroid or asteroid; definitely fits.

  • Nickname for Mars, a real planet in space.

  • Some satellites carry radar instruments in space.

  • Cosmic rays and gamma rays travel through space.

  • Robotic spacecraft and landers are found in space.

  • Common in UK: space rubbish means orbital debris.

  • Radio waves move through space; real phenomenon.

  • A red dwarf is a real small star in space.

  • Space rubble = debris from asteroids or impacts.

  • Late-life massive star phase; very huge and cool.

  • Star that appears red; many giants/dwarfs look red.

  • Plural of red star, common in astronomy contexts.

  • Noble gas detected in lunar/planetary atmospheres.

  • Planets are nearly round objects orbiting stars.

  • Famous icy dust rings orbiting Saturn’s equator.

  • Asteroid drifting free, not bound to one planet.

  • Bright blue supergiant star in Orion constellation.

  • Radioactive element found in trace cosmic materials.

  • Light rays travel through space from stars/galaxies.

  • Propellant powering rockets to reach outer space.

  • A star like the Sun seen as red; stellar object.

  • Small, cool red stars; most common in our galaxy.

  • Iron oxide dust coats Mars regolith, gives red color.

  • Cosmic rays are high‑energy particles in space.

  • Planets, stars and galaxies all have rotation.

  • Can describe a lunar eclipse giving moon a red tint.

  • Ice and rock bands encircling Saturn and other giants.

  • Planets often described by their rotating motion.

  • Rhea is a large icy moon of Saturn, found in 1672.

  • Red dust appears on Mars and in interstellar clouds.

  • Naturally occurs in space from radioactive elements.

  • Retrograde orbits/motion are common in astronomy.

  • Small, cool main‑sequence star; very common.

  • Covers Mir and other Russian crewed orbital stations.

  • Element found in stars and interstellar gas

  • Distinct ice and rock band encircling Saturn

  • Robotic vehicle exploring Mars’ surface

  • Asteroids are common rocky bodies in space

  • Debris from rockets remains in Earth orbit

  • Planetary ring systems like those of Saturn

  • Common term for ring systems around planets

  • Cosmological redshift: light stretched by expansion

  • Could describe a comet glowing red in space

  • Radioactive material exists in stars, space

  • Mars has red sand‑like regolith on surface
