The clouds are made up sulphuric acid with carbon dioxide. This is one angry Goddess, the air is noxious, unbearable, and hot, approaching 900 degrees. The narrator mention that there is nothing can survive on the planet
93. The second planet the movie visited was ___ ___ ___ ___ ___ ___ ___.

The core of the planet is a large iron core.
94. The movie then visited the ___ ___ ___, the star at the center of the solar system, a giant sphere of hydrogen and helium, a nuclear fusion furnace.
95. The third planet visited was ___ ___ ___ ___ . This planet is the fourth planet from the center of the solar system and is also called the red planet. The planet is red and dead. There is wind and when there is wind then there is air. No ozone layer, nothing to protect any creatures who might choose to live there from deadly space radiation. If they have any. It is hard to believe anything could live here because of the kinds of weather that they have. There was also this the largest volcano in the solar system, Olympus Mons, taller than Mount Everest.

There is wind, "rain", many different seasons, rivers, lakes, and oceans, that looks familiar and similar to our own planet which is Earth. And yet they are completely different: rives, lakes, and oceans of liquid methane, natural gas, an atmosphere with nitrogen but no oxygen. There is no way life can develop in on this moon of the ringed planet.
100. Beyond the ringed planet is a planet unknown to the ancients, the planet ___ ___ ___ ___ ___ ___. This is the first planet to be discovered using a telescope. The planet is tipped over at a 98 degree angle, the north pole now facing the sun. 42 years of sunlight will strike the north pole until the sun sets as the planet moves around the sun.

The planet is covered in hydrogen, helium, and methane gas. The planet has very high wind speeds. High winds speeds means that the atmosphere has a lot of kinetic energy. But the planet is too far from the sun for the sun to be the source of the energy. Something else is creating the wind.
102. Beyond this last planet there are no more "full size" planets. The dwarf planet ___ ___ ___ ___ ___ used to be the "ninth planet" but was demoted and is now called a dwarf planet. The surface appears to be frozen water ice and carbon compounds.
