Please go to https://www.solarsystemscope.com/ and click "START"
Take a moment to zoom all the way out and remind yourself of where we are in the rest of space.
Now zoom back in again, and note where there are things like:
Rings of "debris" or small rocky objects
How many planets are closer to te Rā than the first ring of debris
How many planets are farther than te Rā than the first ring of debris.
Click and drag the Solar System so you can see it from the side, then drag it to the right or left.
Notice that the signs of the zodiac that we saw in lesson 10 are the constellations that are in line with the rest of the Solar System. We call this plane the "ecliptic."

What is a Whetūao (planet)?
What is a Whetūao (planet)?
A whetūao is a round object in space that orbits around a star. It doesn't make its own light.
The main conditions on any planet depends on:
the distance from the Sun
the amount of atmosphere
what type of elements the planet is made of.
These planets were each noted by cultures all around the world, and many attempted to discern the meaning behind their movements. Thousands of years later, we now know that the orbit of the planets is what causes them to appear to move compared to the background stars.
Dwarf Planets
Dwarf Planets
Dwarf planets are small rocky worlds. They have strange orbits that don't have enough mass to clear the area around their orbits.
Ceres is a dwarf planet, and the dwarf planets that are past Neptune are called plutoids. We now have four objects that we call plutoids, and they are Pluto, Eris, Haumea, and Makemake. Some of the other things shown here might be called dwarf planets or plutoids in the future.
Asteroids, Comets and Meteors
Asteroids, Comets and Meteors
Other particles never gathered enough material to become planets or dwarf planets. Instead, they remained orbiting around the Sun as other kinds of objects., such as asteroids and comets.
