We extend a Jovian convective-cooling model to Uranus and Neptune. The model assumes that efficient interior convection prevails, so that escape of interior heat is governed by the radiative properties of the atmosphere. A comparison of the thermal evolution of Uranus and Neptune indicates that the...
In Chart Comparison (Synastry) In the Composite Chart Uranus sextile Neptune When Uranus and Neptune connect, we want to shake up the status quo. We can be visionary and inspired. In the Natal Chart With Uranus forming a sextile to Neptune in the birth chart, you’re open to raising...
A similar instrumental concept may be feasible for the exploration of origin, dynamics and chemistry of the stratospheres of Uranus and Neptune. The development status of SWI and the potential application of the instrument and its concept for the exploration of the two ice giants will be ...
Although Uranus and Neptune are significantly larger than the terrestrial planets, their radii are less than half those of the largest planets, Jupiter and Saturn. For additional orbital and physical data about Uranus, see the table. Because Uranus’s spin axis is not perfectly parallel to the ...
We present an analysis of X-ray observations of the trans-Jovian planets Saturn, Uranus and Neptune with the ROSAT PSPC in comparison with X-ray observations of Jupiter. For the first time a marginal X-ray detection of Saturn was found and 95% confidence upper limits for Uranus and Neptune...

The brightnesses of Titan, Uranus, and Neptune in b (4718 A) and y (5508 A) have increased linearly since 1972 at rates ranging from 0.005 to 0.025 mag yr 1. The observations were made differentially on a number of nights each season with respect to a network of comparison stars whose...
With a radius of 25,362±7 km (about 15,760 miles), Uranus is the third-largest planet in the solar system, after Jupiter and Saturn. It’s the fourth, behind Neptune, by mass, though. Its average distance from the Sun is roughly 20 AU (3 billion km or 2 billion miles, see note...
Astronomers have discovered two tiny moons orbiting Neptune and one circling Uranus, bringing the number of their known moons to 16 and 28 respectively.
