Solar System
The closest planet to the Sun
What is Mercury?
What is rotation?
The axial tilt of Earth.
What is 23 degrees?
The moon was likely formed through this event.
What was a collision with a Mars-sized object?
This measures the force exerted based on gravity.
What is weight?
The type of planet found closer to the Sun.
What are rocky planets?
Completing an orbit around another object.
What is a revolution?
During summer months, the Sun's rays are striking the Northern Hemisphere in this way.
What is directly?
A half-moon with the right side illuminated is called this.
What is a first quarter moon?
This is a measurement of the amount of matter in an object.
What is mass?
The dwarf planet around which the moon Charon revolves.
What is Pluto?
The idea that the sun and planets all formed at the same time from a rotating cloud of gas
What is Nebular Theory?
The astrological event that happens in March and September when there is 12 hours of day and 12 hours of night.
What is an equinox?
The most powerful form of tide.
What is a spring tide?
The strength of gravitational force between objects is directly proportional to this.
What is the mass of the object?
The asteroid belt is located between these two planets.
What are Mars and Jupiter?
Flattened debris caused by rotational velocity.
What is an accretion disk?
The longest day of the year.
What is the summer solstice?
The moon is said to be "tidally locked" for this reason.
What is a rotational velocity equal to its orbital period?
The speed that an object must achieve to break away from the gravitational pull of an object.
What is escape velocity?
The furthest reaches of the solar system where most comets are located.
What is the Oort Cloud?
The planet with the longest revolutionary period.
What is Neptune?
This inner planet has an axial tilt of 177 degrees, meaning that it has no seasons.
What is Venus?
A location near the South Pole of the moon with a crater 21 km wide.
What is Shackleton?
The strength of the gravitational force between object in inversely proportional to the square of this factor.
What is the distance?
