The two #rings of (50000) #Quaoar: https://arxiv.org/abs/2304.09237 - besides secondary events related to already reported rings Q1R, new secondary events detected during a August 2022 #occultation in three different data sets are consistent with another ring around Quaoar with a radius of 2520±20 km, assuming the ring is circular and co-planar with Q1R; this new ring has a typical width of 10 km and a normal optical depth of ∼0.004. Like Q1R, it also lies outside Quaoar's classical Roche limit.

"A dwarf planet beyond Neptune has a mysterious ring that astronomers can't explain

The ring is so far from the dwarf planet's surface that its material should have coalesced into a moon. But somehow, it didn't."

#Quaoar"

Perhaps the solar wind and CMEs push away the material that would normally form rings around inner planets. Also, many rings are composed of ice which would not exist nearer the Sun.

The Sun's gravity may also play a factor.

Astronomen vinden een ring rond Quaoar

De nieuw gevonden ring draait op een afstand van 7,4 * de straal van Quaoar in het object heen. Dat is in verhouding veel verder dan de ringen rond Saturnus.

Another dwarf planet has a ring? C'mon inner solar system, step up your game already.
#Quaoar

Planetary scientists are puzzled by the presence of a ring around a distant #KuiperBelt object. Scientists reported this week the discovery of the ring around #Quaoar, an object a little less than half the diameter of #Pluto orbiting beyond #Neptune. The ring appears to be uneven, varying in width from a few kilometers to a few hundred kilometers.
