Who's Who in the Solar System

I have the greatest range of temperatures of any planet in the solar system. Very hot days and very cold nights. I have a low surface gravity, a thin atmosphere, and lots of craters.which planet am I?

• Mercury

• Mars

• Venus

• Earth

I am an planet that has the largest volcano in the solar system called Olympus Mons. My atmosphere is very thin and my surface is cold. I have polar ice caps of frozen water and carbon dioxide. I also have seasons because I am tilted on my axis as I revolve around the sun. Which planet am I?

• Mercury

• Mars

• Venus

• Earth

I am a planet that is about the same as Earth. I have a thick atmosphere of mostly carbon dioxide this causes my surface temperature to be the hottest of any other planet at 464 degrees C. I also have clouds of sulfuric acid and lots of active volcanoes. My pressure is 90 times that of Earth and I have retrograde rotation (backwards). Which planet am I?

• Earth

• venus

• Mars

• Mercury

I am the only planet in are solar system known to have liquid water and life forms. I have seasons because I am tilted on my axis as I revolve around the sun. My atmosphere protects the surface from the sun's radiation and creates a constant range of temperatures. Which planet am I?

• Earth

• Venus

• Mars

• Mercury

I am a planet who was discovered by mathematical prediction. I have visible clouds in my atmosphere which consist of hydrogen, helium, and methane. I have many storms because of the difference in my core temperature and my cloud temperature. Because of the temperature differences my wind speed often reach 2000 km/hour. Which planet am I?

• Neptune

• Uranus

• Saturn

• Jupiter

I am a frozen ball of rock and ice. I have a very thin atmosphere of nitrogen, methane and carbon monoxide gases. My surface is 98% frozen nitrogen, some methane and carbon monoxide. I am one of the furthest from the sun and have been demoted to dwarf status. Which planet am I?

• Neptune

• Kuiper Belt

• Pluto

• Ceres

I am the largest planet in the solar system. My gravitational force is 3 times that of Earth and my pressure is 30 million times greater than the Earth’s surface. I am known for my red spot which is a storm. I am made of mostly hydrogen and helium. Which planet am I?

• Saturn

• Neptune

• Jupiter

• Uranus

I am made of mostly hydrogen and helium with methane, ammonia, and ethane in my upper atmosphere. My density is .70 which is less than the density of water. I have the most rings of any other planet in the solar system. One of my major moons is called Titan. Which planet am I?

• Jupiter

• Saturn

• Neptune

• Uranus

I am the smallest of the outer planets with a bluish-green color. My atmosphere is primarily hydrogen and methane gas. I have a top to bottom rotation unlike other planets that rotate side to side. Which planet am I?

• Jupter

• Neptune

• Uranus

• Saturn

I am a chunk of rock or dust in space. When I enter the Earth’s atmosphere I am heated by friction until I glow. Many of my kind burn up before we reach the Earth’s surface. What am I called when I am burning in the atmosphere?

• Meteor

• Meteorite

• Asteroid

• Comet
