It is called the Sagittarius dwarf spheroidal galaxy, or Sgr for short.Sgr, which loops in and out of the Milky Way once every 760m years, is able to traverse it in this way because the individual stars of both galaxies are so far apart.
In one type, called S modes, or spheroidal vibrations, the motions of the elements of the sphere have components along the radius as well as along the tangent.
The virus particle is enveloped in a fatty membrane; is variable in shape, from spheroidal to filamentous, and in size, from 60 to 300 nanometres (1 nanometre = 10-9 metre) in longest dimension; is studded with spikelike protein projections; and contains ribonucleic acid (RNA).
In the chondrites (stony meteorites), the olivine is commonly incorporated in the distinctive spheroidal bodies referred to as chondrules, which range up to one millimetre in diameter.
During the year Rodrigo A. Ibata and Gerry Gilmore of the University of Cambridge and Mike Irwin of the Royal Greenwich Observatory, Hailsham, England, discovered a dwarf spheroidal galaxy only about 50,000 light-years from the Sun.
The virions of reoviruses (the name is a shortening of respiratory enteric orphan viruses) lack an outer envelope, appear spheroidal, measure about 70 nanometres (nm; 1 nm = 10-9 metre) across, have two icosahedral capsids, and contain a core of segmented, double-stranded RNA.
The virus particle lacks an envelope, is spheroidal, measures from 20 to 30 nanometres (nm; 1 nm = 10 - 9 metre) across, and is covered with subunits called capsomeres.
These SG (spheroidal graphite) irons, which are also called ductile irons, are strong and malleable; they are also easy to cast and are sometimes preferred to steel castings and forgings.
The inner ear consists of a series of hollow interconnected parts: the semicircular canals; the ovoidal or spheroidal chambers called the utriculus and sacculus; and the lagena, a small outgrowth of the sacculus.
Nevertheless, the two Propositions that proved most important were 19 and 20, which respectively derive the non-spheroidal figure of the Earth and the variation of surface gravity with latitude under the assumption that the density of the Earth is uniform.
Many virions are spheroidal actually icosahedral the capsid having 20 triangular faces, with regularly arranged units called capsomeres, two to five or more along each side; and the nucleic acid is densely coiled within.
