Solar System List

This is a list of solar system objects by radius arranged in descending order of mean volumetric radius this list is not exhaustive.

Solar system list. Solar energy system a solar energy system is a renewable energy generating system that collects photovoltaic energy from the sun and converts it into usable electricity. There are currently 181 known moons in our solar system orbiting the various planets and dwarf planets. The solar system s several billion comets are found mainly in two distinct reservoirs. It contains the sun the planets several natural satellites and a number of other notable objects.

The following is a list of solar system objects by orbit ordered by increasing distance from the sun most named objects in this list have a diameter of 500 km or more. As the term is applied to bodies in earth s solar system the international astronomical union iau lists eight planets orbiting the sun. The inner solar system and the terrestrial planets. The more distant one called the oort cloud is a spherical shell surrounding the solar system at a distance of approximately 50 000 astronomical units au more than 1 000 times the distance of pluto s orbit.

It consists of the sun and eight official planets including neptune uranus saturn jupiter mars earth venus mercury more than 130 satellites of the planets at least three dwarf planets many comets and asteroids. Mars mars was a wet and warm planet billions of years ago. The ordering is not the same as the order of a list of solar system objects by mass because some objects are denser than others. Pluto also was listed as a planet until 2006.

The solar system formed 4 6 billion years ago. The sun a spectral class g2v main sequence star. Earth the only planet in our solar system with liquid water on the surface. These are the planets mercury and venus and the dwarf planets ceres and makemake.

Venus venus thick atmosphere makes it the hottest planet in our solar system. This is a list of selected planets. Of the 13 planets and dwarf planets there are four which don t have any moons. Often found as roof top pv arrays these systems can range in size and are able to power different types of properties such as residential commercial and utility scale zones.

In a highly controversial decision the international astronomical union ultimately decided in 2006 to designate pluto as a dwarf planet reducing the list of the solar system s true planets to. Moons in the solar system.
