How many types of planets are in our solar system? What are they?
There are three types of planets: inner planets, outer planets, and dwarf.
What is the first law?
The First law is That all planets move around the sun in elliptical orbits, having the sun as the focus/ rotation point.
What is Venus?
Venus is an inner planet that has a high temperature and is the second from the sun. It is made of rock and was formed from dust and gas.
What four planets make up the outer planets?
Jupiter, Saturn, Uranus, and Neptune.
How many dwarf planets are there?
There are 5 that we have discovered. Ceres, Pluto, Eris, Makemake, Haumea.
What are two similarities between inner and outer planets?
Both inner and outer planets orbit the sun and were formed around the same time as each other.
What is the second law?
The second law is that a planet covers the same area of space in the same amount of time no matter where it is in orbit
What is the order that the 3 types of planets go?
The way that the planets go are inner, outer, then dwarf planets.
Where are the outer planets?
All Four of the outer planets are behind the asteroid belt.
Do any dwarf planets have moons?
Yes, Pluto has 5 moons and Eris has one.
What are two differences between inner and dwarf planets?
Dwarf planets have not become entirely round because they don't have good enough gravity, inner planets have. Dwarf planets also have not cleared their orbit path.
What is the third law?
The third law states that a planet’s orbital period is proportional to the size of its orbit
What are the inner planet's surfaces made up of?
The inner planets' surfaces are made up of rock and other solid materials that can be found in the ground.
What are the outer planets primarily made of?
They are mainly made up of hydrogen and helium.
Do any dwarf planets have rings?
Only one has one that we have discovered as of now. Haumea.
What are three similarities between the outer and dwarf planets?
Both inner and dwarf planets orbit around the sun, they are both rocky, and neither of them are satellites.
Why were Kelper’s laws invented?
They were invented to define what a planet is compared to what a dwarf planet is.
What are Terrestrial planets?
These planets are called Terrestrial planets because they are able to be inhabited by living creatures if the temperature is right.
What are two characteristics of the outer planets that nothing else in our solar system has?
They have planetary rings and various amounts of moons.
Why haven’t Dwarf planets cleared their orbit?
They have other objects near them of about the same size that they can’t clear out of their orbit because they don’t have enough gravity
What are three differences between the inner and outer planets?
Inner planets are formed by a simple amount of dust and gas and outer planets are made from a rocky core that gradually collects the objects around it to form. Inner planets are smaller than the outer planets are. The outer planets are past the astroid belt, while the inner planets are closer to the sun.
What led to the discovery of these laws?
The thing that led to the discovery of the laws is when his teacher passed and he received the equipment of his passed teacher. Using a telescope he discovered the movement of the planets.
How did the inner planet form from nothing?
The inner planets formed from gas and dust particles that gradually got bigger over time and slowly formed by the particles gradually growing bigger and pulling objects towards it.
Can the outer planets be slip up further? If so, how?
Can be spit up into two groups: gas giants and ice giants (all are considered gas giants) The ice giants are the two farthest from the sun: Neptune and Uranus.
What classifies a dwarf planet?
They don’t have a cleared orbit and they may not have become cylindrical under their own gravity yet.
