Krillion Space Answers and Hints

How Krillion Space answers work

Krillion Space answers depend on the class of object or relationship a question asks for.

These questions come from the free game on this site. Each timed prompt accepts one guess. Use the clue to recall a set, then choose an answer you can type confidently. The metres in the lists follow our practice scoring.

Name one of the five officially recognized dwarf planets.

Hint: Four are beyond Neptune. One is in the asteroid belt.

100 m: Pluto.
250 m: Ceres, Eris.
500 m: Haumea, Makemake.

NASA lists Ceres, Pluto, Haumea, Makemake, and Eris as the five officially recognized dwarf planets. Ceres is in the asteroid belt, while the other four are beyond Neptune. Pluto is the familiar practice answer and earns 100 metres. Ceres and Eris earn 250 here. Haumea and Makemake earn 500. The wording matters because scientists also discuss objects that are candidates for dwarf planet status. For this prompt, use the recognized group. You can recall Ceres separately and then work through the four farther out.

Name one of the four Galilean moons of Jupiter.

Hint: All four were observed by Galileo in 1610.

100 m: Europa, Io.
250 m: Ganymede.
500 m: Callisto.

The Galilean moons are Io, Europa, Ganymede, and Callisto. Io and Europa sit in the 100-metre practice tier, Ganymede earns 250, and Callisto earns 500. Jupiter has many more moons, but those four form the group named in the question. A correct answer to “name a moon of Jupiter” can be wrong for this narrower prompt. One recall method is to learn the four in order outward from Jupiter. Once you have the order, choose a name you can spell reliably before the timer runs out.

Name a planet whose orbit lies beyond the asteroid belt.

Hint: Start just after Mars and skip over the asteroid belt.

100 m: Jupiter, Saturn.
250 m: Neptune.
500 m: Uranus.

After the main asteroid belt between Mars and Jupiter, the planet sequence continues with Jupiter, Saturn, Uranus, and Neptune. This is a question about the position of each planet's orbit, so a giant planet does not need to be the furthest one to count. Remember the pair of gas giants first, then the pair of ice giants. Neptune earns 250 metres and Uranus earns 500 in this practice pool. Pluto is beyond the same belt and still falls outside the prompt because this question asks for planets.

Name a known moon of Pluto.

Hint: Its largest companion is much better known than the four small moons.

100 m: Charon.
250 m: Hydra, Nix.
500 m: Kerberos, Styx.

Charon, Styx, Nix, Kerberos, and Hydra are Pluto's known moons. Charon is much larger than the others and is usually the easiest name to retrieve. The other four are a useful set to rehearse separately. When entering Kerberos, use the spelling shown in the table. A similar-looking name from mythology may not be an accepted form. A good recall exercise is to say the parent body, list its satellites, and then check that you didn't borrow a moon from another part of the solar system.

How to recall Krillion Space answers

Krillion Space answers are easier to find when you separate an object's classification from its location.

Identify the relationship before naming an object

Space questions often ask you to distinguish the object itself from a group or relationship. Ceres fits the dwarf planet question. Europa fits the Galilean group and orbits Jupiter. Uranus fits a question about the orbit of a planet beyond the asteroid belt. The names alone won't tell you which category to use. When a prompt includes a parent body, a classification, or a location, take a moment to recall that constraint first. A name associated with the same region of the solar system is a weaker candidate than one you can place in the specified set.

Make two short lists for the moon questions

Write Jupiter on one line and Pluto on another. From memory, place Io, Europa, Ganymede, and Callisto on the Jupiter line. Then add Charon and the four smaller moons under Pluto. Try retrieving the list in both directions by looking at a moon name and saying which body it orbits. This helps with timed rounds because you can reject a candidate that belongs on the other line. Don't worry about learning every Jupiter moon for this exercise. The question on this page asks for the four Galilean ones.

Separate the location clue from the classification clue

Ceres is inside the asteroid belt and belongs to the recognized dwarf planet group. Jupiter is beyond the belt and belongs to the planet group. Pluto is beyond Neptune but still belongs with the dwarf planets in the first question. Read both parts of a prompt that names a location and a type. If you only check the location, Pluto looks plausible for the outer planet question. If you only check the object type, Earth looks plausible as a planet. Combine the two conditions before choosing.

Take the higher tier when the name is certain

Charon is a good quick answer. Hydra or Nix can earn 250 metres when you recall a smaller moon of Pluto, and Styx or Kerberos can earn 500. The tiers are editorial practice scores, so they do not change with the popularity of a guess on the official site. If you missed because two names sounded similar, use the table once to check the spelling. Then cover it and try recalling the full name without a visual clue.

Give yourself a backup answer

Try naming one solar system object you will recognize immediately and a second you can justify in one sentence. For the Galilean prompt, Europa could be your first choice and Callisto your backup. For the asteroid belt prompt, Jupiter gives you a planet just beyond the belt and Neptune gives you one farther out. This exercise is useful when the same class of question appears after a break. The backup only helps if you can explain its membership without the table.
