Comparing Exoplanets sizes

Comparing exoplanets sizes. Come with me on a journey to compare the sizes of a number of different exoplanets. In this video we shall look at the sizes of exoplanets and compare them to each other and to the Earth. Exoplanets come in a variety of categories. Firstly we have sub-earths. These exoplanets are considerably smaller than the planet earth. Next we have the super-earths. Earth like planets just bigger. There are also ocean worlds such as maybe Kepler 22b and mini Neptune. We also have gas giants and even brown dwarfs. In this video we will pay a fleeting visit to a great many of these.
