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.
Where is the earth?
The Earth is the third planet from the Sun in our solar system, and it is located in the Milky Way galaxy. It is part of the inner solar system and orbits the Sun at an average distance of about 93 million miles.
The nebular hypothesis suggests that our solar system evolved from a huge?
The nebular hypothesis suggests that our solar system evolved from a huge rotating cloud of gas and dust called a solar nebula. Over time, gravity caused the nebula to collapse and spin faster, forming the sun at the center and the planets and other objects in orbit around it. This process is supported by evidence from observations of other star systems and the composition of our own solar system.
Is planetary accretion still occurring?
The planets grew from the impact of innumerable smaller bodies early in the history of the solar system. This process is called planetary accretion. The early history of the terrestrial planets is marked by continuous collisions with larger and larger planetary bodies. Accretion was essentially complete by 4.56 billion years ago. Meteorites and asteroids are materials left over from the formation of the solar system that have not yet accreted to a planet. Accretion continues even today at a very slow rate whenever a meteor falls to Earth.
The earth is made mostly of metals and rocks Where did this material come from?
The materials that make up Earth, including metals and rocks, were formed during the process of planetary accretion from the solar nebula about 4.6 billion years ago. These materials condensed and accumulated to form the Earth as we know it today. Rocks are composed of various minerals, which are made up of elements like silicon, oxygen, aluminum, iron, and other metals that were present in the early solar system.
Which one is the biggest the planetary system or galaxy?
A galaxy is far larger. A planetary system involves one or more planets revolving around a single star. A Galaxy consists of billions of stars.
What order do these go in Galaxy Universe Solar System Planet Star Nebula Largest to smallest?
Universe, galaxy,nebula,solar system, star, planet
Is the Milky Way galaxy the solar system you live in?
NO we live in eagle Nebula
Which is biggest out of the solar system space or galaxy?
In order from smallest to largest: Solar System, Galaxy, and Space.
What is the difference between a planetary nebula and a nebula that formed the solar system?
The solar system did not form from a nebula at all. Our solar system formed from a rotating cloud of gas and dust, our sun formed at the center and planets formed from the surrounding matter. when our sun became large enough to support nuclear fusion, the solar wind created blew away most of the gases present. A planetary nebula is formed after a star runs out of fuel (Helium) and collapses inward on itself due to the massive amount of gravity and the now unstable balance of the star. the pressure then becomes so great that the gases that had been pulled inward explode outward at an incredible speed. The Cats Eye Nebula is a good exampleFile:NGC7293_(2004).jpg
What is the largest planetary moon in the universe?
well since astronomers cant see all of space its impossible to andswer but the biggest in our solar system i believe is Ganymede of Jupiter, in the galaxy the largest is appartently also ganymede
Are the solar system and all the stars in the space part of your galaxy?
The solar system definitely is, and most of the stars you see are as well. If you can see the Andromeda Nebula on a very dark clear night, that is a system of stars outside our galaxy.
Why is it called planeterium nebula?
I think you mean, planetary nebula. They are balls of gas and plasma. The name originated with their discovery in the 1700s because of they looked similar to planets when viewed through small telescopes. They are not related to the planets of the solar system.
Is a galaxy part of your solar system?
No, it's the other way around; our solar system is a (very tiny!) part of our Galaxy. Our galaxy is many BILLIONS of stars, most of which probably have (or perhaps, once had) some sort of planetary or asteroid system in orbit around them. Scientists once thought that planetary systems like our solar system would be scarce. But recent discoveries have found planets circling many or most of the nearby stars.
Are planetary system common?
Yes, planetary systems are common in the universe. Nearly every star observed so far has been found to have at least one planet orbiting around it, suggesting that planetary systems are a common feature in the galaxy.
What is bigger moon solar system meteorite comet star galaxy universe?
Obviously, the Universe is the biggest of that lot. Next biggest is "galaxy", then solar system, then star, then moon. A comet is usually bigger than a meteorite, but not always.
What are the universe rankings from smallest to largest?
The universe can be organized in various scales: Planetary system (e.g. our solar system) Galaxy (e.g. Milky Way) Galaxy cluster (group of galaxies) Supercluster (groups of galaxy clusters) Observable universe (everything we can potentially observe)
