Space Revision and Concepts Quiz

Space Revision

• A light year is the distance light travels in a year
• The moon is a natural satellite that orbits Earth
• A planet is a circular object orbiting a star (like the sun)
• Mercury is the smallest and closest planet to the sun
• Venus is the hottest planet
• Earth is the only known place with water and life
• Mars is known as the red planet
• Jupiter is the largest planet and has a large red spot
• Saturn has rings and approximately 150 moons
• Uranus is a tilted planet
• Neptune has rains of diamonds
• Pluto is not a planet, but a dwarf planet located in the Kuiper belt

Comets, Meteors, and Meteorites

• Comets are dust particles frozen in ice that orbit the sun
• Meteors are dust and rock moving through the sky
• Meteorites are any type of meteor that has fallen on Earth
• Asteroid belts are a belt full of rock and stone and sit between Mars and Jupiter
• A solar system is a system that has a star and planets

Solar Eclipse

• A solar eclipse occurs when the moon passes between the sun and Earth
• The moon casts a shadow on Earth during a solar eclipse
• The umbra is the darkest part of the shadow
• The penumbra is the outer part of the shadow
• A solar eclipse will only be noticeable if the sun, Earth, and moon are perfectly aligned

Lunar Eclipse

• A lunar eclipse occurs when Earth passes between the sun and the moon
• Earth casts a shadow on the moon during a lunar eclipse
• There are two types of lunar eclipses: partial and total
• Partial lunar eclipses occur when only part of the moon enters Earth's umbra
• Total lunar eclipses happen when the entire moon enters Earth's umbra, causing the moon to appear reddish (blood moon)

Diagram of Sun, Earth, Moon, and Comet

• Diagrams illustrating the relative positions of the Sun, Earth, Moon, and a comet

Calculating Gravitational Field Strength

• A method for calculating gravitational field strength, mass, and weight using a triangle
• Steps for finding unknown values (mass, G, W) involve multiplication and division using the correct units. Weight (W) should be used first when dividing.
