What is the definition to planetary system?
A system of celestial bodies grouped around a sun.
What percentage of all planetary matter in the solar system is in Jupiter's mass?
Jupiter contains about 70% of the total planetary mass in our solar system, making it by far the most massive planet. It is primarily composed of hydrogen and helium, the most abundant elements in the universe.
Why do nebulas happen?
The same reason why most things happen; gravity. Every speck of matter in the universe attracts every OTHER speck of the universe with gravity. So a a large thin cloud of gas in space will, over time, become a smaller thicker cloud of gas. Given enough gas and enough time, the cloud will collapse under its own gravity to form a star, or a planetary system. But if all the gas is attracted in all directions, why would it all fall together HERE, rather than OVER THERE - and since the gas is all over, why would it collapse at all? We think that the shock of a somewhat-distant supernova explosion begins the collapse process by pushing enough gas together for gravity to finally do its thing.
What is a central star with planets around it?
A central star with planets around it is a planetary system or a star system. The central star, often a sun-like star, is orbited by planets that may vary in size, composition, and distance from the star. The arrangement of planets around the central star is known as a planetary or solar system.
What makes a star a sun?
A star is considered a sun when it is the central star of a planetary system, such as our own Sun in the Solar System. The term "sun" is typically used to refer to the star at the center of a specific planetary system, providing light and energy to its orbiting planets.
Is it true that nebulas are the best first ingredient for building a new planetary system?
That is a true statement; large nebulas contain enough mass to make several star systems.
What term is applied to any star that is the center of a planetary system?
A sun is a star that is the center of a planetary system.
What three gears make up a complete planetary gear system?
The gears in a planetary gear system are the drive gear, ring gear, and planetary gear.
Which is biggest a planetary nebula a planetary system or a galaxy?
A galaxy is the biggest among the three. Galaxies contain billions to trillions of stars, as well as other celestial objects like planets and planetary nebulae. A planetary system refers to a star with its orbiting planets, while a planetary nebula is a glowing shell of gas ejected by a dying star.
What is the name of our planetary system?
Our planetary system is called the Solar System, named after the Sun (Latin: Sol) around which all the planets, moons, asteroids, and other celestial bodies orbit.
What is planetary accretion?
Planetary accretion is the process by which smaller particles in a planetary system collide and stick together, gradually building up larger bodies like planets. This process is driven by gravity, as particles attract each other and form into increasingly larger objects over time. Accretion is a key step in the formation of planets from the protoplanetary disk around a star.
