Solar System Basics
This is the name for a group of planets and other objects orbiting the Sun.
What is the solar system.
This animal was the first to orbit the Earth.
What is a dog.
This natural rock object orbits a planet, such as Earth.
This term describes the amount of matter in an object.
What is mass?
This planet is the largest in our solar system.
What is Jupiter?
These are two examples of objects found in the solar system that are NOT planets.
What are moons and asteroids.
One benefit of space exploration is this improvement in technology and knowledge.
What is better communication or scientific understanding.
This icy ball of dust and gas orbits the Sun and has a visible tail.
What is a comet?
This term describes the force of gravity acting on an object.
What is weight?
Of Jupiter, Mars, Uranus, and Neptune, this is the only one that is not a gas giant.
What is Mars?
This massive ball of hot gas sites at the centre of the solar system.
What is the Sun.
This object, which can be natural or artificial, orbits a planet.
What is a satellite?
This small space rock burns up in Earth's atmosphere when it enters.
What is a meteor?
This is the key difference between mass and weight.
What is mass stays the same everywhere, but weight depends on gravity?
This planet is first in line from the Sun.
What is Mercury?
This planet is the closest one to the Sun.
What is Mercury.
These are two challenges or disadvantages of space exploration.
What are high cost and risk of human life.
This star gives off light and heat and is the largest object in our solar system.
What is the Sun?
This would happen to your weight—but not your mass—on Mercury.
What is it would decrease due to lower gravity?
This gas giant has rings and is second in size only to Jupiter.
What is Saturn?
This gas giant is known for its large rings.
What is Saturn.
These are two benefits and two drawbacks of using technology for space exploration.
What are better weather forecasts and communication, and high cost and pollution?
This object is often confused with a comet, but unlike a comet, it burns in the atmosphere.
What is a meteor?
This explains why your weight would be more on Jupiter and less on the Moon, but your mass would not change.
What is gravity affects weight, not mass?
This was the name of the meteor that exploded over Russia in 2013.
What is the Chelyabinsk meteor?
