Irrespective of the material composition of the celestial body, a diameter of a few hundred kilometres is sufficient to create a spherical form – the largest asteroids, Ceres and Vesta, already have a pronounced round shape. It was the first The spherical shell is like a bubble Universe with a space-time in it that, rather than having a flat geometry as our Universe does, will have a spherical geometry (and spherical symmetry, so the only important variable will be the distance r from the sphere's center).

Few papers in astronomy receive over 2,000 citations, though more will in the future as the number of astronomers grows. Since we use angle measurement in the spherical sky, we can also apply standard techniques of geometry. Along the way he offers the greatest expositions yet of number theory, combinatorial topology, the analytics of complexity, and his own groundbreaking work on spherical astronomy. Euclid's Phaenomena described spherical astronomy. This is the ancient science of spherical astronomy. (DLR) - The heavens were divine in origin and, as a consequence, had to be perfect in structure and form; hence the astronomers of antiquity sought to discover perfect geometrical forms in t. I could have added something about it's relationship to nearby M86, perhaps comparing the two and noting that M84 is more spherical with a slightly brighter core while M86 is slightly less bright with a more oblong shape. Celestial objects that are too small for gravity to pull them into spherical shape can have a variety of shapes. The shape of celestial bodies – not perfect. This was crucial, as it is well established that astronomy formed the basis of primitive physics.
