The sun is one of hundreds of billion of stars in our galaxy, the Milky Way. The galaxy is composed of gaseous interstellar medium, neutral or ionized, sometimes concentrated into dense gas clouds made up of atoms molecules, and dust. All of the matter -- gas, dust, and stars -- rotate around a central axis perpendicular to the galactic plane. The centrifugal force caused by the rotation balances out the gravitational force, which draw all the matter toward the center.
The mass is located within the circle of the Sun's orbit through the galaxy is about 100 billion times the mass of the Sun. Because the Sun is about average in mass, astronomers have concluded that the galaxy contains about 100 billion stars within its disk.
All stars in the galaxy rotate around a galactic center but not with the same period. Stars at the center have a shorter period than those farther out. The Sun is located in the outer part of the galaxy. The speed of the solar system due to the galactic rotation is about 220 km/s. The disk of stars in the Milky Way is about 100,000 light years across and the sun is located about 30,000 light years from the galaxy's center. Based on a distance of 30,000 light years and a speed of 220 km/s, the Sun's orbit around the center of the Milky Way once every 225 million years. The period of time is called a cosmic year. The Sun has orbited the galaxy, more than 20 times during its 5 billion year lifetime. The motions of the period are studied by measuring the positions of lines in the galaxy spectra.

What is the period of a planets revolution can be used to calculate the planet?
The period of a planet's revolution is the time that it takes to complete one revolution around its axis of rotation relative to the background stars (also known as rotation period).
What is mars' revolution period around the sun?
687 days.
What is a planetary revolution?
A revolution is the period it takes for the planet to revolve one time around the sun. Its otherwise known as the planet's year.
Whats the time' it takes to move once around the sun called?
The period of revolution or orbital revolution. For Earth, this is one year.
Do the planets revolve around the direct center of the sun?
The center of the orbit is between them in proportion to their masses. But the mass of the sun is so much larger compared to the mass of the planets that to a casual observer they do revolve around the center of the sun. Because planets don't orbit the exact center of stars, astronomers can see stars that "wobble" and can tell they have planets orbiting them. They will also get an idea of the period of those planets' revolutions around the star.
The earth and your solar system is orbiting the center of the milky way galaxy?
Yes, with an orbital period of around 220 million years.
What is the period revolution of the sun?
The sun does revolve in the Galaxy, but the period at which a single revolution would occur would be hundreds of millions of years. The sun spins every 25 days.
What is the period of revolution for the moon?
From the point of view of a person on earth, the moon's period of rotation on its axis and revolution around earth are both 27.32 days. From the point of view of a person on the moon, the period of rotation on its axis and revolution around earth are both 27.32 [earth] days, and the period of revolution around the sun averages 365.24 earth days.
What is the period revolution for the moon?
From the point of view of a person on earth, the moon's period of rotation on its axis and revolution around earth are both 27.32 days. From the point of view of a person on the moon, the period of rotation on its axis and revolution around earth are both 27.32 [earth] days, and the period of revolution around the sun averages 365.24 earth days.
Why does the sun not have a year?
A "year" is defined as the time required for a planet or other object to complete a single revolution around the star it is orbiting. The Sun is itself a star, so it has no other star around which to orbit. The "galactic year", the period of time for the Sun to completely orbit the center of the Milky Way galaxy, is estimated at from 225 to 250 million Earth years.

The period of a planet's revolution is the time that it takes to complete one revolution around its axis of rotation relative to the background stars (also known as rotation period).
What is the period of earth's movement around the sun called?
revolution
What is mars' revolution period around the sun?
687 days.
Does the mass of a planet affect its period of revolution around the Sun?
No, it does not.
What is Mercury's period of revolution around the sun?
88 days
Which planet has the longest period of the revolution around the sun?
Neptune.
What orbits the Sun and how long does it take?
The sun orbits around the center of the galaxy. The orbital period is approximately 235 million years.
