Time to practice! Are you ready for your first Space Quest? Use the buttons below to guide you through the practice quiz. The sun with the group of celestial bodies that revolve around it universe planet galaxy apparent magnitude star absolute magnitude light year solar system Next Question All of space and everything in it universe planet galaxy apparent magnitude star absolute magnitude light year solar system Next Question A unit of distance equal to the distance that light travels in one year universe planet galaxy apparent magnitude star absolute magnitude light year solar system Next Question A major body (not a comet or asteroid) orbiting around a star universe planet galaxy apparent magnitude star absolute magnitude light year solar system Next Question The brightness of a star if it were a standard distance from Earth universe planet galaxy apparent magnitude star absolute magnitude light year solar system Next Question A large collection of stars, gas and dust held together by mutual gravitation universe planet galaxy apparent magnitude star absolute magnitude light year solar system Next Question The brightness of a star as seen from Earth universe planet galaxy apparent magnitude star absolute magnitude light year solar system Next Question A natural, luminous, celestial body universe planet galaxy apparent magnitude star absolute magnitude light year solar system Next question How are galaxies (mainly) classified? by size by shape by color by brightness Next Question How is an elliptical galaxy different from a spiral galaxy? Elliptical galaxies have almost no gas or dust Spiral galaxies have almost no gas or dust Spiral galaxies contain only old stars none of the above Next Question The hottest stars are …. red white blue none of the above Next Question The two gases that our sun is made of are…. hydrogen and oxygen oxygen and carbon dioxide hydrogen and helium helium and carbon dioxide Next Question The region of the sun responsible for producing light is… the corona the photosphere the core the chromosphere Next Question The main characteristics used to classify stars are… age, brightness and size brightness, color and temperature brightness, temperature and size brightness, age and temperature What’s next? OOPS! Sorry, but that term does not match the definition. Try again! Click the button to return to the question. Return to question ALL RIGHT! The sun with the group of celestial bodies that revolve around it is called a SOLAR SYSTEM! Keep moving! ALL RIGHT! All of space and everything in it is the definition of the UNIVERSE! Keep moving! ALL RIGHT! A unit of distance equal to the distance that light travels in one year is called a LIGHT YEAR! Keep moving! ALL RIGHT! A major body (not a comet or asteroid) orbiting around a star is also known as a PLANET! Keep moving! ALL RIGHT! The brightness of a star if it were a standard distance from Earth is called the star’s ABSOLUTE MAGNITUDE! Keep moving! ALL RIGHT! A large collection of stars, gas and dust held together by mutual gravitation is what scientists call a GALAXY! Keep moving! ALL RIGHT! The brightness of a star as seen from Earth is called the star’s APPARENT MAGNITUDE! Keep moving! ALL RIGHT! A natural, luminous, celestial body is better known as a STAR! Keep moving! ALL RIGHT! Keep moving! Congratulations! You have just successfully completed the vocabulary practice for your upcoming science quest. Keep reviewing and best of luck to you! The End
