Where did most of the interplanetary fragments in the outer solar system get flung to by the larger gas planets?

Expert Solution

According to the condensation theory:

Over a period of hundreds of millions of years, many interplanetary fragments in the outer Solar System were thrown out by the jovian planets to the edge of the Solar System. These interplanetary fragments form a theoretical cloud of predominantly icy planetesimals known as Oort cloud.

The Oort cloud is proposed to surround the Sun at distances ranging from 2,000 to 200,000 AU (0.0 to 3.2 ly). It is divided into two regions: a disc-shaped inner Oort cloud (or Hills cloud) and a spherical outer Oort cloud. Both regions lie beyond the heliosphere and in Interstellar space.

The outer limit of the Oort cloud defines the cosmographical boundary of the Solar System and the extent of the Sun's Hill sphere. The outer Oort cloud is only loosely bound to the Solar System, and thus is easily affected by the gravitational pull both of passing stars and of the Milky Way itself.

The orbital region of Earth is known as the Goldilocks region in our solar system where the probability of life to exist is higher than any other regions which may be too hot or too cold. My question: Why did we make such a wild assumption that, for life to exist we need a neither hot nor cold region or there has to be oxygen and water? There might be alien life which require say Plutonium or Mercury to live....

A solar collector design consists of an inner tube enclosed concentrically in an outer tube that is transparent to solar radiation. The tubes are thin walled with inner and outer diameters of 0.08 and 0.10 m, respectively. The annular space between the tubes is completely enclosed and filled with air at atmospheric pressure. Under operating conditions for which the inner and outer tube surface temperatures are 80 and 30°C, respectively, what is the rate of convective heat loss per meter...
