For OSRS shooting stars, the main thing that increases how much stardust you get is mining lower-tier stars first, especially tier 1 and tier 2 stars, because dust output drops as the star tier goes up. A guide also notes that the Celestial ring gives a +4 invisible Mining boost, which helps efficiency, though it does not directly change the stardust formula.

What matters most

  • Star tier: lower tiers give more stardust per hour than higher tiers.
  • Your Mining speed/uptime: better mining efficiency means more total dust over time, even if the dust per action stays the same.
  • Competition on the star: more players mining the same star can make it deplete faster, which can reduce your total dust if you arrive late or on higher tiers.

Practical tip

If your goal is maximum stardust, people usually chase fresh low-tier stars rather than big, heavily mined ones. If your goal is just chill AFK mining, higher tiers can still be fine, but they tend to be worse for dust per hour.

Shop angle

Stardust is mainly spent on rewards like the Celestial ring and star fragments from the Shooting Stars shop. The ring is one of the most useful buys because it gives that Mining boost.

TL;DR

More stardust comes from mining lower-tier stars , getting there early , and having better Mining efficiency; the Celestial ring helps your Mining, but the big factor is star tier.
