@ToughSf Eris’s moon Dysnomia also shares its name with a disorder that I can’t think of as I type this. 🐇 🕳️ Looked up how they figured out Eris’s mass and Hubble helped analyze the wobble from Dysnomia for the math.

@ToughSf It is not really the up to date limit, it is the one cryptographers know about. The Mandelstam-Tamm and Margolus–Levitin theorems are more relevant. https://t.co/z2p4GTO8hb 623 views · 15 likes · 0 reposts · 0 replies 06 Sep 2026 · Open on X →

The Bremermann's limit is the maximum rate of computation possible in a self-contained system. It's 1.356 x 10^50 bits per second per kilogram. An Earth-mass computer is limited by physics to cracking a 256-bit key in two minutes. https://t.co/L1L5COVWtz 4.1K views · 98 likes · 4 reposts · 1 replies 06 Sep 2026 · Open on X →

@ToughSf Eris at its perihelion shines at magnitude +14.5, much brighter than Pluto at aphelion (+16.3). Where the orbits be located differently in the XX century, Eris would have been the ninth planet instead of Pluto. Eris reached aphelion in 1977, while Pluto perihelion in 19 224 views · 4 likes · 0 reposts · 0 replies 06 Sep 2026 · Open on X →

Eris is actually 25.7% heavier than Pluto. It has a shiny white surface, while its moon Dysnomia, a quarter of its size, is very dark with an albedo of just 0.05. This strange pair orbits between 38.1 and 97.49 AU from the Sun. https://t.co/T9pLpaJVBJ 10.6K views · 388 likes · 43 reposts · 3 replies 05 Sep 2026 · Open on X →
