The dipole magnetic moment of Neptune is about 2.2 × 10 17 T·m 3 (14 μT·R N 3, where R N is the radius of Neptune). Neptune's magnetic field has a complex geometry that includes relatively large contributions from non-dipolar components, including a strong quadrupole moment that may exceed the dipole moment in strength.
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
This template is to show size comparison of Jupiter, Neptune and the Earth alongside extrasolar planets that have their radial size confirmed. {{ Planetary radius | radius = <!--simplified number of the radius (Jupiter equals 100px)--> }}
Vesta (radius 262.7 ± 0.1 km), the second-largest asteroid, appears to have a differentiated interior and therefore likely was once a dwarf planet, but it is no longer very round today. [74] Pallas (radius 255.5 ± 2 km ), the third-largest asteroid, appears never to have completed differentiation and likewise has an irregular shape.
A sphere (top), rotational ellipsoid (left) and tri-axial ellipsoid (right) The mean radius in astronomy is a measure for the size of planets and small Solar System bodies . Alternatively, the closely related mean diameter ( D {\displaystyle D} ), which is twice the mean radius, is also used.

Neptune is 17 times the mass of Earth and is slightly more massive than its near-twin Uranus, which is 15 times the mass of Earth and slightly larger than Neptune. [a] Neptune orbits the Sun once every 164.8 years at an average distance of 30.1 astronomical units (4.50 × 10 9 km).
I’m right-handed, like most people. For just that reason, Conestoga wagons had the controls on the left side, close to the wagon driver’s right hand. That meant the driver was toward the ...
