# Neutron stars in Cassiopeia — page 2 of 3

What a massive star's core becomes when it stops holding itself up: a sphere the width of a city with half again the Sun's mass, spinning, and magnetised past anything else known.

## The table

50 neutron stars inside the IAU boundaries of [Cassiopeia](https://spacecatalog.org/constellation/cassiopeia.md), sorted by name. Rows 21–40, page 2 of 3.
