Uranus is skewed, too — but to a much greater extent. In relation to its orbital plane, Uranus'' axis has been tilted at a jaw-dropping 97.7-degree angle. Uranus is the only planet in the solar system with its equator nearly at a right angle to its orbit. Next to other giant planets Saturn and Neptune, Uranus appears to be on its side.

In Depth | Sun – NASA Solar System Exploration

Our solar system is moving with an average velocity of 450,000 miles per hour (720,000 kilometers per hour). But even at this speed, it takes about 230 million years for the Sun to make one complete trip around the Milky Way. The Sun rotates on its axis as it revolves around the galaxy. Its spin has a tilt of 7.25 degrees with respect to the

Optimal design and cost analysis of single-axis tracking

In such a system, one of the axial movements, typically the horizontal axis, can be accomplished using a slew drive.The primary goal of a dual-axis solar tracking system is to ensure that the

Axis of evil (cosmology)

The "axis of evil" is a name given to an unsubstantiated correlation between the plane of the Solar System and aspects of the cosmic microwave background (CMB) gives the plane of the Solar System and hence the location of Earth a greater significance than might be expected by chance – a result which has been claimed to be evidence of a departure from the Copernican

Solar Rotation Varies by Latitude

The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots. The Sun''s rotation axis is tilted by about 7.25 degrees from the axis of the Earth''s orbit so we see more of the Sun''s north pole in September of each year and more of its south pole in March.

Axial tilt

OverviewSolar System bodiesStandardsEarthExtrasolar planetsSee alsoExternal links

All four of the innermost, rocky planets of the Solar System may have had large variations of their obliquity in the past. Since obliquity is the angle between the axis of rotation and the direction perpendicular to the orbital plane, it changes as the orbital plane changes due to the influence of other planets. But the axis of rotation can also move (axial precession), due to torque exerted by the Sun on a planet''s equatorial bulge. Like Earth, all of the rocky planets show axial precession

Axial tilt

The positive pole of a planet is defined by the right-hand rule: if the fingers of the right hand are curled in the direction of the rotation then the thumb points to the positive pole.The axial tilt is defined as the angle between the direction of the positive pole and the normal to the orbital plane. The angles for Earth, Uranus, and Venus are approximately 23°, 97°, and 177° respectively.
