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.
What is the Tidal theory about the origin of the earth?
One theory is the Big Bang - after that, matter, including Earth, formed inside a solar nebula which later became our Sun.
Describe characteristics of the universe in terms of time distance and organization?
Organization: The part of the universe closest to Earth is the solar system. This system compromises of Earth, the sun and other planets. But also smaller objects like dwarf planets, asteroids, and comets. The solar system is part of a galaxy (an assembly of stars dust and gases which are brought together by gravity). The galaxy where the solar system is, is the Milky Way galaxy. Past the Milky Way galaxy, there are many more galaxies. Time/Distance: The universe is mostly measured in astronomical units since the units used on Earth are too small to measure the universe. An astronomical unit ,Au, is the average distance between the Earth and the sun. This is about 149,597,870.691 km or 150 million km. They also use the speed of light to measure distance. Light moves at 300,000 km/s. In a year light travels 9.46 × 1012 km. The distance is a light-year.
What science studies earth and space systems?
Many different scientific disciplines could be used to answer your question. Astrophysics studies planetary motion, stellar motion, the movements of comets, asteroids, etc (when applied to the solar system). Astronomy studies celestial bodies and the universe as a whole. Cosmology studies the history of the cosmos which includes a detailed study of our own solar system. Stellar evolution studies the life (formation, evolution, death) and kinds of stars. Etc. Many disciplines could answer your question. I hope this helped.
Where was the calcium in your teeth made?
Your teeth do have calcium in them, but in a low concentration. If they were pure calcium, then the calcium would react with the air and saliva in you mouth and violently explode, shooting flames and most likely killing you.
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
A group of stars gases and dust?
A galaxy or a nebula.
Is it true or false that nebula's are the first ingredient for building a new planetary system?
This is false. The first ingredient is God.
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 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.
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
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.
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.
