You are a space explorer who is on an expedition of scientific discovery to another galaxy. Unfortunately, your space ship was damaged by an asteroid and needs to make an emergency landing. Quick scans reveal three possible planets your ship could land on. Based on the information in the table below, how do you convince your shipmates of the planet that would have a force of gravity which is most similar to Earth's? Planet Name Radius of Plant Mass of Planet (compared to Earth) (compared to Earth) Ares Twice the radius Half the mass Borros Half the radius One fourth the mass Caeto One third of the radius Nine times as much mass "We should go to Borros. Since it has half the radius, the gravity would be stronger, but since it is only one fourth the mass, the changes balance out and the gravity will be the same as on Earth." 1) "We should go to Caeto. Since it has three times the radius, the gravity would be weaker, but since 2) it is nine times as much mass, the changes balance out and the gravity will be the same as on Earth." "We should go to Ares. Since it has twice the radius, the gravity would be stronger, but since it 3) only has half the mass, the changes balance out and gravity would be the same as on Earth."

You are a space explorer who is on an expedition of scientific discovery to another galaxy. Unfortunately,
your space ship was damaged by an asteroid and needs to make an emergency landing. Quick scans reveal
three possible planets your ship could land on. Based on the information in the table below, how do you
convince your shipmates of the planet that would have a force of gravity which is most similar to Earth's?
Planet Name
Radius of Plant
Mass of Planet
(compared to Earth)
(compared to Earth)
Ares
Twice the radius
Half the mass
Borros
Half the radius
One fourth the mass
Caeto
One third of the radius
Nine times as much mass
"We should go to Borros. Since it has half the radius, the gravity would be stronger, but since it is
1)
only one fourth the mass, the changes balance out and the gravity will be the same as on Earth."
"We should go to Caeto. Since it has three times the radius, the gravity would be weaker, but since
2)
it is nine times as much mass, the changes balance out and the gravity will be the same as on
Earth."
"We should go to Ares. Since it has twice the radius, the gravity would be stronger, but since it
