1. Can someone help me with this? :) Which object is made of frozen gas, ice, and dust that orbits in the outermost reaches of t
he solar system? 1) planet 2) moon 3) Kuiper Belt object 4) meteor
2. Which explanation of the solar system best fits the observations of the planets and how they orbit the sun? 1) A comet hit the sun and sent off fragments that became the planets. 2) The gravity of a large, massive star passing the sun ripped off blobs of material from it that formed the planets. 3) The planets formed at the center of a collapsing spinning cloud of gas and dust. 4) The sun and planets formed from a collapsing spinning cloud of gas and dust.
<span>1. Kuiper Belt object is made of frozen is made of frozen gas, ice, and dust that orbits in the outermost reaches of the solar system. Kuiper belt is a region which is filled with icy gaz bodies. Its structure is almost the same as the asteroid belt between Mars and Jupiter. Pluto, Makemake, Haumea are the officially recognized planets which are located in this region.
2. In my opinion, the most suitable option is: 3) The planets formed at the center of a collapsing spinning cloud of gas and dust. According to theory of solar system formation, the solar system appeared after a supernova (star explosion). A cloud of gas and dust was collapsed, and it caused a formation of a solar nebula.
There is no sound in space because there is no medium to move it. However i think the big bang can still been seen in the form of background radiation but i am unsure.
