Satellites, Moons, Comets, and Orbits (Unit 1: Objects In Space)
Terms in this set (18)
Any object that orbits a planet or a star.
Moons and rings
Our Moon's name, in English:
"The Moon" [and sometimes, Luna]
The shape of every orbit:
An object orbiting the Sun speeds up when this is happening:
An object is approaching the Sun (or whatever it is orbiting)
The reason orbiting objects speed up and slow down:
Sometimes an orbiting object is moving in the same direction that gravity is pulling it, and sometimes it is moving against the gravitational pull.
A "dirty snowball," made of rock and ice.
This is what causes a comet's tail to form:
When a comet gets close to the Sun, the sun heats up the comet's ice and blows its ice and dust away from the comet in a long trail.
The direction in which a comet's tail points:
Away from the Sun
The objects in our solar system that have the least circular, most elliptical orbits:
The Oort Cloud:
The most distant part of the Solar System, where comets spend most of their time. Beyond the Kuiper Belt.
The number of years for comet Neowise (visible in July of this year) to return and be visible again:
The planet that is smaller than Jupiter's moon, Ganymede:
The month when the Earth is closest to the Sun.
The longest season in Vermont, and the reason it is the longest:
Summer, because we are farthest away from the sun during our summer, so we are in the slowest part of our orbit.
The largest known comet is this many miles across:
The distance from Earth to The Moon, in light seconds:
The reason comets spend most of their time in the Oort Cloud:
Objects in the Oort cloud are very far from the Sun, so they orbit very slowly when they are there and stay there for a long time.
