Satellites of our solar system.

Solar system assemblage consisting of the sun and those bodies orbiting it. 19 of them are large enough to be gravitationally rounded. Sun is considered. Pluto haumea makemake and eris.

The earth moon system is unique among planetary systems in that the ratio of the diameter of the moon to. Planets and asteroids in our solar system orbit the sun. The four inner or terrestrial planets mercury venus earth and mars have rocky compositions and densities greater than 3 grams per cubic cm. Water has a density of 1 gram per cubic cm.

Of these all are covered by a crust of ice except for earth s moon and io. 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. The solar system s planets and its most likely dwarf planets are known to be orbited by at least 219 natural satellites or moons.

Several of the largest ones are in hydrostatic equilibrium and would therefore be considered dwarf planets or planets if they. The solar system consists of the eight planets that orbit our sun and other celestial bodies such as moons comets asteroids minor planets and dust and gas. In addition to these spacecraft some third stages and de spin. There are more than 200 moons in our solar system.

8 planets with about 170 known planetary satellites. Comets and other icy bodies. The eight planets can be divided into two distinct categories on the basis of their densities mass per unit volume. Let s consider the satellites or moons of the planets in particular 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. 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. And vast reaches of highly tenuous gas and dust known as the interplanetary medium. With applications for mac and pc as well as apps for mobile devices there are many ways for you to follow along with our scientists and engineers.

The exploration of these moons is one of the pinnacle achievements in the space program. Moons also known as natural satellites orbit planets and asteroids. As of september 2018 there are 334 other minor planets known to have moons. Four iau listed dwarf planets are also known to have natural satellites.

Countless asteroids some with their own satellites. Solar system solar system planets and their moons. The position of the planets moons and spacecraft are shown where they are right now. 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.
