A group of planets revolving around a star is called?
A group of planets revolving around a star is called a solar system. Each planet orbits the star in the center of the system and together they form a celestial family held together by gravity. The most well-known solar system is our own, which consists of eight planets orbiting the Sun.
A solar system is much smaller than?
a galaxy. A solar system consists of a star (like our sun) and planets, moons, asteroids, and comets orbiting around it. A galaxy, on the other hand, is a vast system of stars, dust, and dark matter held together by gravity.
What is the system of billions or stars held together by gravity?
A system of billions of stars held together by gravity is called a galaxy. The one we live in is called the Milky Way galaxy.
What is the role of galaxies stars and planets in your solar system?
In *my* solar system, galaxies play no role, as my solar system is just one of many solar systems that make up our galaxy. A single star, which we call the Sun, is the most massive object in our solar system and, to a pretty good approximation, all of the planets in our solar system orbit around the Sun. What are the roles of the galaxies, stars, and planets in *your* solar system?
Milky way made of?
The Milky Way is a barred spiral galaxy that contains billions of stars, dust, and gas. It is held together by gravity and has a central bulge surrounded by a disk. Our solar system resides in one of the spiral arms of the Milky Way.
What is the solar system held by?
^^Inertia ^^
Is the solar system a galaxy?
No, the solar system is not a galaxy. The solar system is a small part of the Milky Way galaxy, which is a collection of billions of stars, planets, and other celestial objects held together by gravity.
A group of planets revolving around a star is called?
A group of planets revolving around a star is called a solar system. Each planet orbits the star in the center of the system and together they form a celestial family held together by gravity. The most well-known solar system is our own, which consists of eight planets orbiting the Sun.
How can you use the word inertia in a sentence?
Brian was amazed that the shack still stood. It seemed to be held together by mud, spiderwebs, and inertia.
How are all of the planets in the solar system held?
My teacher Mrs. Black said before that it was gravity that holds the planets together in space.
How is the the solar system held in orbit?
Every member of the solar system is held in orbit around the sun by the mutual force of gravity between the object and the sun.
Why does the sun belongs in the solar system?
Solar refers to the Sun. It has a system of planets and other things orbiting around it, held in their orbit by the Sun's gravity. Without the Sun, there is no solar system.
A solar system is much smaller than?
a galaxy. A solar system consists of a star (like our sun) and planets, moons, asteroids, and comets orbiting around it. A galaxy, on the other hand, is a vast system of stars, dust, and dark matter held together by gravity.
When did Isaac Newton find out that the solar system was held by gravity?
1665
What does 'system' mean as in the 'solar system'?
Generically a "system" can be described as group of interacting, interrelated, or interdependent elements forming a complex whole.The sun, its planets and their moons are all a balls of matter held together by (or interacting by means of) gravity. As such they form a "system" as with the above definition.This system is called the "solar system" because the largest member of the system the Sun (which makes up over 99% of all the matter in the system) is a star called "Sol" and therefore the system is named after it - solar system.
Are the planets held in their orbits by unbalanced forces?
No. The planets are held in orbit by forces balanced against each other: The force of gravity from the sun would pull the planet into the sun destroying it. The momentum of the planet making it travel in straight line would result in the planet travelling away from the solar system. There are also other forces involved such as the pull from other planets on each other. Combined, they balance each other resulting in a planets circular/elliptical path orbiting the sun. Otherwise, the planet would have fallen into the sun, collided with other planets or other objects, or just flown away from the solar system long ago and we would never have known about it.The force that holds objects in orbit is gravity. In the case of our solar system, the planets are held in orbit by the gravity generated by Sol, our sun (a sun is a star with a satellite system).The inertia of the planets combined with the Sun's gravity keeps the planets in orbit. So, there's only really one force, gravity. However, the effect of inertia is sometimes referred to as "centrifugal force", although its not a real force.Objects in our solar system are kept from falling into Sol, the sun, by their centripetal motion (inertia). They are kept from flying off into empty space by Sol's gravity, generated by spacial displacement.They are held in orbit by the gravity of a celestial body of a greater mass. For example, the planets in our solar system are held in orbit by the gravity of the sun.
What is the system of billions or stars held together by gravity?
A system of billions of stars held together by gravity is called a galaxy. The one we live in is called the Milky Way galaxy.
