Arrival

As the planet got closer and closer, the blue marble became exceedingly vibrant. 

The slime was already floating close to the window as it looked out into space.

"What is that?" it asked, pointing towards the planet with its translucent blue hands.

"That? That is a moon," Ning explained. "Did your planet not have moons?" 

"No," the slime said. "Ours did have a massive ring going around the planet though. I didn't see it in the last planet, and now this planet has rings. Are all planets like this?" 

"Sort of," Ning explained. "Some have nothing. Some have satellites, some have rings. Some are even made up of entirely gas. There are probably way more that I don't even know about."

As the planet got closer, the slime could see all the blue in it and was surprised at how much water was on this planet.

As the spaceship entered the planet's atmosphere, it slowed down heavily as the thrusters immediately started doing their job.
