<span>The minor body that orbits the outside of the Neptune is the planet, Pluto. It slipped along the orbit of Neptune for it to be called as the ninth planet. However, this planet around 248 years to orbit along the sun, which is why it doesn't usually cross paths with Neptune.</span>
Jupiter, Uranus, Neptune, and Mars.
The correct answers are:
Planet A 16 hours - Inner planet.
Planet B 1,408 hours - Outer planet.
The inner planets are the ones that are much closer to the sun, thus they have much smaller orbits around it and it takes them much less time to circle around it. Also, these planets are much smaller, which enables them to spin around their axis much quicker too, so one day passes much quicker.
The outer planets are the total opposite. They are much further from the sun, so for them to be able to make a single circle around the sun it takes much more time, and also, because they are much bigger, it takes them much more time to spin around their own axis, thus making one day much longer than the days of the inner planets.
Some of the factors would be introduction of non native species, pollution, overgrazing, chemical agents and habitat loss
