One complete orbit takes 365.249 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi). [2] As seen from Earth, the planet's orbital prograde motion makes the Sun appear to move with respect to other stars at a rate of about 1° eastward per solar day (or a Sun or Moon diameter … See more Earth's orbit is an ellipse with the Earth-Sun barycenter as one focus and a current eccentricity of 0.0167. Since this value is close to zero, the center of the orbit is relatively close to the center of the Sun (relative to the size … See more Because of Earth's axial tilt (often known as the obliquity of the ecliptic), the inclination of the Sun's trajectory in the sky (as seen by an observer on … See more Mathematicians and astronomers (such as Laplace, Lagrange, Gauss, Poincaré, Kolmogorov, Vladimir Arnold, and Jürgen Moser) … See more • Earth – Speed through space – about 1 million miles an hour – NASA & (WP discussion) See more Heliocentrism is the scientific model that first placed the Sun at the center of the Solar System and put the planets, including Earth, in its orbit.

Orbital Periods of the Planets - Space Facts
WebLHS 3844 b is a rocky Earth sized lava world with an 11-hour orbital period. It was one of the first exoplanets to be discovered by TESS.Credit: NASA/MIT/TESS WebWe use Equation 13.7 and Equation 13.8 to find the orbital speed and period, respectively. Solution Using Equation 13.7, the orbital velocity is v orbit = G M E r = 6.67 × 10 −11 N · m 2 /kg 2 ( 5.96 × 10 24 kg) ( 6.36 × 10 6 + 4.00 × 10 5 m) = 7.67 × 10 3 m/s which is about 17,000 mph.
