As a result, it has a pronounced equatorial bulge, causing the star to assume an oblate spheroidal shape.
The spheroidal shape of the Earth is the result of the interplay between gravity and centrifugal force caused by the Earth's rotation about its axis.
In the inner few kpc ( 10,000 light-years) is a dense concentration of mostly old stars in a roughly spheroidal shape called the bulge.
Due to conservation of angular momentum, this led the gaseous interstellar medium to collapse from a roughly spheroidal shape to a disk.
It was an irregular shape, roughly spheroidal, two hundred and forty kilometers wide--the size of a large asteroid.
Instead, the graphite in the iron formed into spheroidal shapes, and the cast iron had high tensile strength plus it exhibited ductility.
The study also showed that Grahamchapman itself has a rotation period of about 2.3 hours, and probably has a nearly spheroidal shape.
Because of the oblate spheroidal shape of this star, the polar region is at a higher temperature than the equator-23,000 K versus 17,600 K respectively.
All are too small to have attained a gravitationally-collapsed spheroidal shape.
These features, and Dactyl's spheroidal shape, imply that the moon is gravitationally controlled despite its small size.
