There are about 408 multiple-planet solar systems in our galaxy. The orientation of these solar systems are on a flat plane due to lacking giant planets, where as ours is tilted off the solar system's plane because of Jupiter's gravitational influence..
The solar system is , in fact, a type of system.
A galaxy. Our solar system, along with billions of others, is in our galaxy.
Because it has an atmosphere.
The solar system is only a small part of a galaxy. The Milky Way, galazy in which our solar system is found, has other solar systems.
We strongly suspect that every other solar system will be different, probably RADICALLY different, from our own. Every star is a little different; the mass that coalesced to form the solar system is different, and the unimaginably random factors that caused each solar system to form as it did - those are also different.
Very different
Sirius is not part of our Solar System, so it is not appropriate to talk about "other objects in the solar system".
yes but they are outside our solar system in our Solar system are only 8 the others are dwarf planets Edit: May 8th 2013 There are 11 in our close range solar system but millions outside our univerese or solar system. Remember space is infinite.
Moon, Milky way galaxy, mars and many others.
Our solar system consists of the sun, the planets, their moons, and a variety of smaller objects. The sun is at the center of the solar system, with other orbiting around it. The force of gravity holds the solar system together.
The different parts of the Solar System attract one another through gravity. Since the Sun has most of the mass of the Solar System, other objects are mainly attracted to the Sun.
"solar system" is the term used to describe planets orbiting a star. We know that planets also orbit binary and tertiary star systems, these would be different kinds of solar systems.
