Earths inner core is the innermost geologic layer of planet EarthIt is primarily a solid ball with a radius of about 1220 km 760 mi which is about 20 of Earths radius or 70 of the Moons radius.
. The stellar halo is a nearly spherical population of field stars and globular clustersIt surrounds most disk galaxies as well as some elliptical galaxies of type cDA low amount about one percent of a galaxys stellar mass resides in the stellar halo meaning its luminosity is much lower than other components of the galaxy. There are no samples of Earths core accessible for direct measurement as there are for Earths mantle.
