Orbital Period: Venus orbits the Sun at an average distance of about 0.72 AU (108,000,000 km/67,000,000 mi) with almost no eccentricity. In fact, with its farthest orbit (aphelion) of 0.728 AU (108,939,000 km) and closest orbit (perihelion) of 0.718 AU (107,477,000 km), it has...
this period lasts 365.25 days – a period that we refer to as a year. When it comes to the other planets, we use this measurement to characterize their orbital periods. And what we have found is that on many of these planets, depending on their ...
Image 1.0 Sunspots at the beginning of the 2017 Total Solar Eclipse The Solar Sunspot Cycle The solar maximum (the period when the Sun has the maximum sunspot count) of last six cycles occurred in 2012, 2001, 1990, 1979, 1968, and 1957. In each case, the solar maximum extended over man...

Use Kepler’s Third Law to find its orbital period from its semi-major axis. The Law states that the square of the period is equal to the cube of the semi-major axis 2=23 In order for the units to be correct, the semi-major axis should be in astronomical units, and the period sho...
The Moon has an orbit period of 27.3 days and an orbital radius of 3.84×108m. Find the orbital velocity of the moon in m/s. Circular Motion: The rate of change of angular position of a particle with respect to time is called angular speed. The relation between t...

FIGURE 1. Geometry of the ellipse. The period of an elliptical orbit (the time required for one revolution) is computed from Kepler's second law: the radius vector sweeps out equal areas in equal times. The constant “areal rate” swept out by the radius vector is dA/dt = h/2, where...
