Reduced motion is on: instant results, no confetti.
For large lists, the wheel shows sectors without text. Read the full choices in the list and the selected result on the card.

How it works
- The browser chooses an entry using cryptographic randomness with rejection sampling. Every remaining line has one chance; repeating a line gives that choice additional chances. The wheel animation presents the result already chosen.
- Choices and results are processed in this tab and are not automatically saved or uploaded. This is a casual selection tool, not a certified lottery or a prediction of real outcomes.
Assumptions and limitations
The pool uses the eight-planet solar system classification. Pluto is a dwarf planet and is not in this set; the Sun and Moon are not planets either. The draw does not simulate orbits, visibility or space-travel feasibility.
How to use this tool
Review the choices, select a choice set when offered, and spin. The result card lets you spin again, remove that occurrence or close. Editing the list changes the candidate pool; a new choice set restores its reviewed defaults. Sound, confetti and animation have separate switches.
When to use it
Assign a planet for a short presentation, a model-making activity or a comparison of atmospheres and orbits. The spinner chooses the subject; the next useful step is researching what distinguishes that planet from the other seven.
Included choices
- Mercury
- Venus

Worked examples

Draw a planet for a short presentation
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune form eight entries. Each has a 1-in-8 chance. Jupiter is not more likely because it is larger, and Neptune is not less likely because it is farther away.
