There is plenty of weather on other planets, on Jupiter there is a huge storm big enough to swallow up many Earths, called the great red spot, and it's been going on for 300 years . .
It varies, from one comet to another. Some may go all the way to the Oort cloud. Others have been trapped by one of the outer planets, and don't go much beyond the outermost planets.
The objects that orbit the Sun between the inner and outer planets are collectively known as asteroids. They are rocky remnants left over from the early formation of the solar system. Some asteroids are quite large and have even been classified as dwarf planets, such as Ceres.
No planets have been detected in the Arcturus star system
Pluto is no longer considered a planet. It has been renamed a "dwarf planet" since it shares its orbit with other, similar sized (or larger... Pluto's orbit crosses Neptune's, and Neptune is enormous compared to Pluto) bodies. There are 8 known planets in the Solar System, and it's considered unlikely that more will be discovered if the current guidelines are kept (anything large enough to "sweep out its own orbit" would have a detectable impact on the orbit of Neptune). There are around 500 confirmed "exoplanets" (planets orbiting stars other than the Sun).
Because the larger planets are easier to see, the smaller ones may be there, but not large enough for our modern equipment to accurately detect.
Pluto is round. It is massive enough to have been rounded by it own gravity.
It might have been possible to give some sort of an answer if the question elaborated on the word "THESE". As it is, the only thing that can be said is that they are planets and sothey are large enough to be approximately spherical shaped due to their own gravity,they are small enough so that thermonuclear fusion cannot take place, andthey have cleared planteray building material (planetesimals) from their neighbourhood.
The sun itself contains no planets. It probably has captured enough matter during it's life to make several planets, but this matter would have been vaporised in the intense heat.
New planets are not forming in our solar system. When you get beyond Neptune, there is large grouping of stellar debris called the Kuiper Belt. The Kuiper Belt has enough material to become another planet, but it orbits around the sun too slowly for the material to combine. The planets formed by having asteroid-like rocks collide with one another, and the objects in the Kuiper Belt are spread out too far and don't have enough moment to form anything. There may be new planets forming around different stars. So far there have been around 800 stars found to have planets orbiting them, but there is no indication when those planets were formed. There may be new planets forming around different stars.
Some planets are made completely of layers of thick gases. Also space exploration has not progressed enough to a point where the layers of other planets have been discovered.
Saturn is the least dense of all the Planets. It has been said that if you could find a large enough bath - and water, Saturn would float. This is because Saturn's mean density is lower than water at 0.687 g/cm³
Planets, likely anything with mass, will bend light. More massive planets will bend light more. Under normal circumstances, planets are not massive enough to allow us to clearly see this, but the concept has been shown with stars and our sun, and the principle applies to anything with mass including planetsThe most obvious things which happens to sunlight when it hits a planet is that it will heat the planets' surfaces and/or atmospheres. The sunlight will also be reflected back, which is why we see planets in the sky as large bright lighted "dots", similar to the stars in the sky.
No large enough sample has been prepared to know what the phase is.
They have been known to eat them. Iguanas are a very large prey for spiders. Some spiders are large enough to eat large birds if hungry enough, so the iguanas are not much bigger.
There are two main reasons.Jupiter's gravity perturbed objects enough to prevent them from forming a single objects.There is not enough mass in the asteroid belt to form anything close to the mass of any of the planets, though it may have been different in the early solar system.
