What is the earths yearly orbit around the sun?

Answer 1

The Orbital Period of Sun is 225 Million Years. This is called a Cosmic Year.

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.

Answer 2

The orbital period of the Earth, known as the sidereal year, is the time taken for the Sun (as observed from the Earth) to return to the same position with respect to the stars of the celestial sphere. It is equal to 365.25636042 mean solar days (31,558,149.540 seconds), that is 366.25636042 earth rotations or sidereal days. The sidereal year is 20 minutes and 24 seconds longer than the tropical year, the year of the four seasons. The word "sidereal" means "relating to the stars". It derives from the Latin sidus, meaning "star".

Answer 3

The sun orbits the galactic core once every 225 million years, in its lifetime it has orbited the galactic core around 20 times so far.

Answer 4

365 days, a year
