Venus is the second planet from the sun. Venues is a very bright planet and is a brightest object in the sky after the sun and moon. Venus also looks like a bright star in the morning or in the evening. The surface of the planet is hard to see because of the thick atmosphere, which is filled with clouds that reflect the sunlight. In size venues is slightly smaller than Earth. The internal structure is similar to Earth with a metallic core, rocky mantle and a crust. Venus’s surface is covered in craters, over 1600 major volcanoes, mountains, large highland terrain and vast lava plans.

Atmosphere: Venus’s atmosphere is very thick and hot totally opposites to Earth. Venus’s atmosphere is 90 times heavier than Earths. To imagine this picture a submarine at a depth of 3000ft below the surface, this is what the air is like on Venus. The atmosphere is made up of mainly carbon dioxide 96%, Nitrogen 3.5% and less than 1% makes up for carbon monoxide, argon, sulfur dioxide and water vapour. Venuses is going through the greenhouse effect meaning that the high levels of carbon dioxide in the air is trapped and heated in the atmosphere helps conduct the greenhouse effect. Very small amounts of sun lights (2%) are absorbed into the atmosphere and are reflected by the sulphuric acid clouds. As some sunlight will reach the surface it heats up and emits infrared rays. The carbon dioxide rich absorbed all the energy from the infrared. The temperature is about 460C (860f) and varies no more than a few degrees from the equator line to each pole so this means that venues temperature fairly changes much and stays pretty much consistent through the days and nights.
