A ___________ farther from the Sun not only has a longer orbit than a closer planet does, but it also travels _______ since the Sun’s ________________ pull on it is weaker. Therefore, the larger a planet’s ___________, the longer the planet takes to complete it.
Use four of the words to fill in the blanks
path slower rotation orbit gravitational planet
A _planet_ farther from the Sun not only has a longer orbit than a closer planet does, but it also travels __slower__ since the Sun’s _gravitational__ pull on it is weaker. Therefore, the larger a planet’s _path_, the longer the planet takes to complete it.
