During the 16th and 17th Centuries, the Earth was added to the list of planets when it was realised that it was also orbiting the Sun. Since then, two more planets have been found making a total of eight. These eight worlds orbit the Sun. Most have moons or satellites orbiting them....
The app also provides moon, sun and all major planets' positions on the interactive sky simulation. Fawad announces launch of moon-sighting app Over the next five weeks, we will take an in-depth look at all eight of the major planets, plus a supporting cast of moons, asteroids and comets...
The moon around the Earth or The Earth around the sun Both, actually! When viewed from the north, nearly all of the moons in our solar system revolve in a counterclockwise motion around their respective planets, and all of the planets in our solar system revolve around the sun in a co...
Cassini observations of these Saturnain satellites inform our evolving understanding of the major Uranian satellites. Some, such as Miranda and Ariel, show extensive modification of their surfaces by endogenic processes, which may be analogous to processes operating on Saturn's moons such as ...
Some of the largest moons in the solar system, Ganymede and Titan, are actually larger than Mercury, and there are dwarf planets like Pluto and Ceres that begin to approach a similar size (although they are still significantly smaller). ...
The semimajor axis, denoted as 'a', is an element that defines the type of orbit of a particle in the Solar System. It represents the average distance between the particle and the Sun, and can be positive for a bound orbit or negative for an unbound orbit. The value of the semimajor...

“The sun shines on the moon. But we can only see half of the moon. During a full moon, the entire lit surface is facing us. But for a new moon, the lit surface is pointing away from the Earth.” 1. New Moon New moons are very difficult to see because a new moon is always ...
“The brightness of the different colors of aurora tell us what these moons’ atmospheres are likely made up of,” said de Kleer. “We find that molecular oxygen, just like what we breathe here on Earth, is likely the main constituent of the icy moon atmospheres.” ...
We find that for a number of targets, including the outer planets, their large moons, and bright asteroids, the model created predicts that with short exposure times, high-resolution spectra (R~250, {\lambda} 2.42{\mu}m) could be obtained with signal-to-noise ratio (SNR) of >100 with...
