Who's Who in the Solar System

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 have a tremendous amount of gravitational pull, the strongest of any other object in our solar system. In my core hydrogen is fused together to make helium. This creates heat and light energy that I share with the planets in my solar system. I am known as a middle aged yellow dwarf which is a type of star. Which space object am I?

• Andromeda

• Betelgeuse

• Sun

• Jupiter

I have a main body or head of frozen water, methane, ammonia, and dust. I have a tail that emerges as this object gets closer to the sun during its long, narrow elliptical orbit. I am left over from when the solar system formed. Sometime I can be seen from earth. Some scientist think we come from the Kuiper (ki-per) belt. Which space object am I?

• Comets

• Meteoroids

• Moons

• Stars

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

What type of Galaxy is the Milky Way?

• Spiral

• Elliptical

• Nebula

• Lenticular

This space object revolve around a planet but not all planets have these. Most of these are rocky and covered with craters, some have unique characteristics. What space object am I?

• Moons

• Planets

• Comets

• Asteroids

I am a rocky fragment left over from the formation of the solar system. Most of my kind congregates in a belt between Mars and Jupiter. Some are very small and others are as large as 250 km. I have been known to leave huge craters like the one in Mexico 65 million years ago. Which space object am I?

• Asteroid

• Meteroid

• moon

• Meteor

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 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
