What force brought the material of the solar system together?
Gravity
100
How do we measure Ellipses?
We measure "eccentricity."
100
Three planets known as gas giants because of their large size and low density are...
Jovian - Jupiter, Saturn, and Uranus
100
Arrange the terms "galaxy, star, universe" in order from largest to smallest.
Galaxy, universe, star.
100
What is the Luminosity of the Sun?
1!
200
What are the two types of planets?
Terrestrial and Jovian
200
What is eccentricity?
Eccentricity is how flat or oval an ellipse is.
200
Which is the largest planet in our solar system?
Jupiter
200
Identify the force that causes the accumulation of matter that forms the stars.
Gravity (Bonus points if you mentioned nuclear fusion!)
200
Which planet has the greatest eccentricity of orbit?
Mercury
300
State one specific detail about a planet (questions 7-15). (from Brainpop video)
Answers vary. Students could answer: Does Mercury have water? How hot can Venus get? What causes the red color of Mars? Which planet is the largest in the solar system? How many moons does Saturn have? Why is Uranus tilted on its side? Why was Neptune named after the Roman god of the sea? Pluto is no longer an official planet. What is it now?
300
What is the eccentricity of a PERFECTLY circular orbit? Why?
A perfect eccentricity is 0. The distance between the foci is 0, so 0/any # = 0.
300
What is equatorial diameter?
It is the distance from one side of the earth to the other side at the equator.
300
These group of planets travels (revolves) relatively quickly around the Sun.
Terrestrial Planets
300
Which planet has a "day" that is MOST SIMILAR to Earth's?
Mars (24 h 37 min 23 s)
400
Terrestrial or Jovian planets: Which ones have a greater equatorial diameter?
Jovian planets
400
What is the formula for calculating an eccentricity ellipse?
Distance between the Foci divided by the length of the major axis.
400
Compared to the Jovian planets, terrestrial planets have a: 1. more rocky composition. 2. lower density. 3. more rapid rotation. 4. larger size.
1. more rocky composition
400
Light and other forms of electromagnetic radiation are given off by stars using energy released during:
Nuclear Fusion
400
A star with a Temperature of 13,700 K and a Luminosity of 700 would be classified as a _________________.
Main Sequence Star.
500
Terrestrial or Jovian planets: Which ones have a greater density?
Terrestrial planets
500
When we calculate eccentricity in our universe, one of the foci will always be the ______.
Sun
500
Which planet takes more time to complete one rotation on its axis than to complete one revolution around the Sun?
Venus (a year on Venus is longer than a day on Venus!)
500
