to revolve 1) а) вращаться; вертеться, поворачиваться The earth revolves around the sun. — Земля вращается вокруг солнца. б) вращать; вертеть, поворачивать • Syn: rotate 2) (revolve about / around) вертеться вокруг (чего-л.) The action of the play revolves around the struggle between two women. — Центр сюжета - борьба двух женщин. His life revolves around football.

to rotate 1. 1) а) вращаться б) вращать • Syn: gyrate , revolve , roll , spin , turn , twirl , whirl 2) а) чередоваться; сменяться по очереди б) чередовать; сменять по очереди, rotate 1) to turn or cause to turn around an axis, line, or point; revolve or spin 2) to follow or cause to follow a set order or sequence 3) (of a position, presidency, etc.) to pass in turn from one eligible party to each of the other eligible parties

to cycle - to move in or pass through cycles

to circle - to move in a circle (around)

to orbit - to move around (a body) in a curved path, usually circular or elliptical

to spin - 1) to rotate or cause to rotate rapidly, as on an axis

to spin=to rotate=to revolve=to cycle

to circle=to revolve=to orbit=to go/move around

A star, any massive, self-luminous celestial body of gas that shines by radiant energy generated within its interior. The universe contains trillions of stars, only a very small percentage of which are visible to the unaided eye.

a constellation, a group of stars in the sky named after the pattern they form.

a planet, any body revolving in an orbit around the Sun or around some other star.

nebula, any of various tenuous clouds of gas and dust that occurs in interstellar space. These interstellar clouds are commonly divided into two general classes according to appearance: dark nebulae and bright nebulae. Dark nebulae are extremely dense, cold molecular clouds that contain roughly 50 percent of the entire interstellar matter of a galaxy. Bright nebulae appear as faintly luminous, glowing surfaces. They emit their own light or reflect that of stars in their vicinity.

a black hole, acosmic body of extremely intense gravity from which nothing, not even light, can escape. A black hole can be formed by the death of a massive star. When such a star has exhausted its internal thermonuclear fuels at the end of its life, it becomes unstable and gravitationally collapses inward upon itself. The crushing weight of constituent matter falling in from all sides compresses the dying star to a point of zero volume and infinite density called the singularity. Only the most massive stars become black holes at the end of their lives. Stars with a smaller amount of mass evolve into less compressed bodies, either white dwarfs or neutron stars.

A quasar, any of a class of rare cosmic objects of high luminosity as well as strong radio emission observed at extremely great distances. An enormous amount of radiation is released from a small area at the centre of a quasar.

pulsars are thought to be rapidly spinning neutron stars, extremely dense stars composed almost entirely of neutrons and having a diameter of only 20 km (12 miles) or less. A neutron star is formed when the core of a violently exploding star called a supernova collapses inward and becomes compressed together.

an asteroid, a mass of rock like a very small planet that goes around the Sun in our Galaxy, especially between Mars and Jupiter.

a comet, a small celestial object orbiting the Sun and developing diffuse gaseous envelopes and often long luminous tails when near the Sun. On nearing the Sun, a comet may develop two tails: a plasma tail and a dust tail.

a meteor, a streak of light in the sky that results when a particle or small chunk of stony or metallic matter enters the Earth's atmosphere. The falling object itself that passes into the Earth’s atmosphere is called a meteoroid.

a meteorite, any interplanetary particle or chunk of stony or metallic matter known as a meteoroid that survives its passage through the Earth's atmosphere and strikes the ground.

a meteor shower, entry into the Earth's atmosphere of a number of meteoroids at approximately the same place and time, traveling in parallel paths and apparently having a common origin. Many meteor showers are associated with comets.

a satellite, a natural or artificial object that revolves around a larger astronomical object, usually a planet.

a dwarf star, any star of average or low luminosity, mass, and size. Important subclasses of dwarf stars are white dwarfs and red dwarfs.

globular clusters can be represented as nearly spherical volume of thinly scattered stars and tenuous gas observed surrounding spiral galaxies, including the Milky Way.
