Stardust can be mined from a Shooting Star from the Distractions and Diversions activity. Shooting stars randomly land anywhere on Runescape every 2 hours or so.
Players can help identify the general area where it will land (Asgarnia, Misthalin, etc.) by using a Telescope in a Player-owned house. Once they have mined a crashed star to the middle whilst gathering stardust, they can exchange up to 200 stardust with a Star sprite once every day.
The amount of experience per stardust mined varies by the current level of the crashed star.
Rewards
When 200 stardust is exchanged to the Star sprite in the core of the Shooting Star, the player is rewarded with:
Reward Grand Exchange

In addition, players will also be rewarded with a chance to mine 2 ores at once from any rock for a 15-minute period. This effect is no longer stacked with that of Varrock armour. This has no effect on mining essence or gold.
You will receive the same items but lesser amounts if you exchange less than 200 stardust.
