Satellites Of Our Solar System
Moons also known as natural satellites orbit planets and asteroids.
Satellites of our solar system. Countless asteroids some with their own satellites. The solar system s planets and its most likely dwarf planets are known to be orbited by at least 219 natural satellites or moons. And vast reaches of highly tenuous gas and dust known as the interplanetary medium. Comets and other icy bodies.
Iapetus small moon of saturn is just one example of the moons that cassini has visited up close during its decade long sojourn in the outer solar system. Most orbit the giant planets with saturn and jupiter leading moon counts but even smaller worlds like pluto can have five moons in orbit. 19 of them are large enough to be gravitationally rounded. Several of the largest ones are in hydrostatic equilibrium and would therefore be considered dwarf planets or planets if they.
Solar system solar system planets and their moons. 8 planets with about 170 known planetary satellites. Of these all are covered by a crust of ice except for earth s moon and io. Let s consider the satellites or moons of the planets in particular in the outer solar system.
The four inner or terrestrial planets mercury venus earth and mars have rocky compositions and densities greater than 3 grams per cubic cm. The exploration of these moons is one of the pinnacle achievements in the space program. Planets and asteroids in our solar system orbit the sun. This digital orrery a model of the solar system runs on a light mobile mobile friendly version of nasa s eyes on the solar system software.
Welcome to nasa s eyes a way for you to learn about your home planet our solar system the universe beyond and the spacecraft exploring them. The eight planets can be divided into two distinct categories on the basis of their densities mass per unit volume. This simulated view of our solar system runs on real data. In the solar system there are six planetary satellite systems containing 205 known natural satellites.
In addition to these spacecraft some third stages and de spin. There are more than 200 moons in our solar system. The earth moon system is unique among planetary systems in that the ratio of the diameter of the moon to. Water has a density of 1 gram per cubic cm.
Sun is considered. Below is a list of artificial objects leaving the solar system all of these objects are space probes and their upper stages launched by nasa. Pluto haumea makemake and eris. Moons come in many shapes sizes and types.
Of the major spacecraft voyager 1 voyager 2 and new horizons are still functioning and are regularly contacted by radio communication while pioneer 10 and pioneer 11 are now derelict. Solar system assemblage consisting of the sun and those bodies orbiting it.
