That is dependant on whether it is the right time in the universal calendar, and which point you choose to start the line at
The giant planets of the solar system, are composed primarily of hydrogen and helium, the lightest elements. They formed beyond what is known as the frost line. Within the frost line the sun's radiation was intense enough to strip away most of the lighter elements, leaving behind smaller planets made mostly of rock and metal. Beyond the frost line the planets were able to hold on to this material and grew massive as a result.
The planets formed by ice would be Jupiter and Saturn!!......I think.............;)
The part of the rotating disk within the frost line was formed of rocks and metals. The part beyond the frost line had both the materials within the frost line as well as some gasses such as hydrogen an helium.
The planets formed out of the solar nebular there is no concept of the "first" they all formed slowly at the same time.
A meteorite is a piece of rock that is similar to the material formed into planets. Meteorites are remnants from the early solar system that can provide insights into the processes that formed the planets.
no stupid. now why would we die when the planets line up?
explosions
The planets rotate around the sun in the same order because they all formed from the same spinning disk of gas and dust in the early solar system. This disk had a consistent rotation direction, which was inherited by the planets as they formed. The gravitational pull of the sun keeps the planets in their orbits in this same order.
They believe the planets formed from a disc of gas and dust called a "protoplanetary disc".
All planets are formed form the remains of the solar nebular.
Certainly yes, it meteorite impact formed the same as sites on the other planets.
The gas planets are much more massive than the terrestrial planets and therefore have stronger gravity. It is believed that as they formed many of their moons formed around them much like the planets formed around the sun. Other moons are likely captured asteroids and comets.
