Typically, gases and particular matter aggregate, due to gravity, as these materials spin around a central mass of strong gravity (a star or protostar, usually). Over time, these orbiting masses accumulate enough matter to become a planet.

Why did earth and the other planets in our solar system develop layered structures?
Gravity and heat.
What effect do collisions among planetesimals of greatly varying size have on the formation of planets?
The small ones get to be "swallowed up" by the bigger ones, because of gravity. Eventually, the planetesimals can develop into planets by this process, which called "accretion".
Do all the planets have smaller planets orbiting them?
No. Planets orbit suns, while moons orbit planets. Planets do not orbit planets.
How many types of planets are in space?
There are 7 main classification of Planets. They are classified into the following groups; * Inferior Planets * Superior Planets * Inner Planets * Outer Planets * Terrestial Planets, * Jovian Planets * Gas Giants
Are inner planets known as Terrestrial planets?
Yes because they are rocky planets and the outer planets are known as the gas planets.
How did planets develop?
they deleloped be being born i think=]
Why did earth and the other planets in our solar system develop layered structures?
Gravity and heat.
How do planets develop their spherical shape?
Gravity pulls the asteroids into spheres when they get big enough.
How does gravity develop around a planet?
As planets get bigger, the gravitational pull gets bigger. Mass entails gravity.
Why did the Sumerians record the positions of the stars and planets and develop a calendar?
The Sumerians recorded the positions of the stars and planets and develop a calendar for a couple of reasons. First they believed in a form of astrology where local events could be predicted understanding the heavens. Also, it helped them tell the best time of the year to plant crops.
What software was used to develop Reboot Beastwars and Shadow Raiders AKA War Planets?
I think the software was called Grin
Why did the Sumerian record the positions of stars and planets and develop develop calendars?
this is what i got in my ''journey across time '' book sumerian people watched the skies to learn the best times to plant crops and to hold religious festivals . they recorded the positions of the planets and stars and developed a 12 mouth calendar based on the cycles of the moon

Are there aliens at other planets?
Probably. Astronomers estimated that there are at least 100 billion planets in the galaxy, a good number of which may be similar to Earth. It seems pretty unlikely that Earth would be the only planet to develop life.
Why does Mars have no oceans or signs of life?
Mars is farther from the Sun than the Earth. The requirements to develop life on Mars were far less than on the Earth which had, at the time of the planets' formation, the ideal conditions to develop life.
Which Austrian scientist develop laws describing the motion of planets?
Johannes Kepler developed the laws of planetary motion.However he was German not Austrian.
How did primitive algae make it possible for other planets and animals to develop on earth?
Mainly by photosythesis that converted the CO2 in the poisonous early atmosphere, into oxygen.
