Introduction[]
This is a list of object extremes in Space engine planetary database. An object extreme is an object or feature of an object that is very unusual or has an extreme difference in amount compared to most ordinary objects. It can be anything to moons, planets, stars, to star clusters, nebulas, and even galaxies. Here you can add anything to the list with the biggest to smallest, farthest to closest, etc.
NOTE: This only includes object extremes that are verifiable. (the object extreme has an SE code) It is very much possible that some players unknowingly have found objects that break records here, but have simply not posted them anywhere. If you want to post something that might be an object extreme, you can go to the Space Engine Subreddit, Discord, Forums, other social media platforms or alternatively the comment section. Make sure to include the SE code for your object extreme.
DISCLAMER: The sizes on the list are measured in diameter, not radius.
Rules[]
- An object extreme must have its SE code and version displayed.
- It must be a procedural object (although procedural objects with real parent are allowed).
- It must have a image of that object extreme in a 1:1 image ratio.
- If you want to add an object extreme that is not discovered by you, credit the original discoverer.
- You must add a cite that link to the original website if you want to add an object extreme that you found on the internet.
- Certain SE mods that impact procedural generation are excluded from the list.
- Findings that can be easily discovered are excluded from the list.
