Now think about how a round object rotates. With the exception of comets and other trans-Neptunian objects, the movements of the system members define a disc or frisbee shape. This sequence of events explains the fundamental differences in chemical composition between different regions of the solar system. Near the poles, the spin rate is slow and gets faster as you get closer to the equator.
However, detailed recent studies of the orbits of the planets and asteroids suggest that more violent events occurred soon after, potentially bringing about significant changes in the orbits of Jupiter and Saturn.
How do the movements of the sun and planets reflect the disk shape of the solar fog quiz?
.
Why is the sun fog flattened into a disc?
Close-up of the Orion Nebula obtained with HST, revealing dust and gas disks surrounding newly formed stars. The ordered movements of the solar system are now a direct consequence of the solar system’s beginnings in a rotating, flattened cloud of gas and dust. Solar nebula, gas cloud, from which, in the so-called nebula hypothesis of the origin of the solar system, the sun and the planets are formed by condensation. Most likely, the next step was for the fog to flatten into a disk called a protoplanetary disk. Planets eventually formed from and in this disc.
Swedish philosopher Emanuel Swedenborg suggested in 1734 that the planets were formed from a fog crust that had surrounded the sun and then broken apart.
What are 3 main properties of the solar system that must be considered when developing a model of its formation?
In the disk instability model of planet formation, clumps of dust and gas are linked together early in the life of the solar system. The following nine questions present properties of the solar system that every model of solar system formation must explain. Condensation theory can explain the fundamental differences between the Jovian and terrestrial planets, as the temperature of the solar nebula is expected to decrease as the distance from the Sun increases. The angular momentum problem is that the sun contains virtually the entire mass of the solar system, but makes up almost no angular momentum.
There are certain basic properties of the planetary system that every theory of its formation must explain.
