Astronomy Basics

Subject : science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

9. A spherical region of comets that surrounds the solar system






10. Planets with low densities and are huge gas giants. Jupiter - Saturn - Uranus - Neptune






11. Large group of stars - dust - and gas held together by gravity; can be elliptical - spiral - or irregular






12. The brightness of a star when viewed from Earth

16. Influenced by Copernicus; Built observatory and collected data on the locations of stars and planets for over 20 years






17. A very small star with low temperature - reddish in color






18. A group of stars that form a pattern in the sky






19. A large cloud of dust and gas that can break apart into smaller pieces and form stars






20. The place in the orbit of a planet where the planet is farthest from the sun
