Planets in our solar system can be divided into two main groups,Terrestrial PlanetsandGas Giants. Planets that orbit other stars are referred to asExoplanets. Click on any planet below to find out more about it: The Planets Mercury Facts ...
A disk of gas and dust appears to be an essential part of star formation. Observations show that nearly all very young protostars have disks and that the disks range in size from 10 to 1000 AU. (For comparison, the average diameter of the orbit of Pluto, which can be considered the ro...
There is lots of gas within the stellar disk—after all, hydrogen and helium are the most common elements in stars and in the universe. However, there is considerably less rocky material because only a limited amount was made during star formation. Comparison of confirmed super-Earth planets co...
7. In calling the cloud of gas and dust from which the Sun and all the planets are thought to have condensed “primordial,’ the author means that the cloud was ○immense in size ○composed of similar particles ○present at the very beginning of our solar system’s formation ...
stars. Radio observations will probe the evolution of dust grains up to centimeter-sized “pebbles”, the critical first step in assembling giant planet cores and terrestrial planets, through the wavelength dependence of dust emissivity, which provides a diagnostic of particle size. High resolution ...

Table 1 Frequency of Jupiter-like planets from radial velocities and microlensing surveys Full size table A higher total occurrence rate of planetary companions detected through RV of 52 ± 5% was obtained by Bryan et al.17in their sample of stars having an inner planet. However, while ve...
Honestly, nothing is better than flying through space looking at the planets and stars to me. But there are a few things that I think would make this game the best. First, I was thinking adding exoplanets to stars we have discovered with them, or just auto generate them. Also, free fly...
