the fastest moving planet moving planet in a solar system?

Question

a.the smallest planet
b.any planet, because they all move at the same speed
c. the planet nearest the sun
d. the planet farthest from the sun

Answer 1

Assuming by fastest you mean lateral movement in the orbital path relative to the surface of the sun, the answer is c.

The planet nearest the sun is experiencing the greatest gravitational attraction to the sun and therefore requires the highest lateral velocity to keep from falling into the sun.

Answer 2

The fastest moving planet in the solar system is mercury which is also the planet nearest the sun.Averaging an orbital velocity of 47.87 km per second, Mercury is the fastest-moving planet in our solar system.

Answer 3

Answer: C

The planets closest to the Sun orbit the fastest....so the title of fastest planet goes with Mercury.

The planets with the highest revolving speed about there axis are the gaseous giants.....example, Earth revolves in 24 hrs....Jupiter revolves in 9hrs 55 minutes.

A bodies orbital speed around the Sun also varies depending whether it is at aphelion or perhelion...that is the furthest and closest point in the eliptical orbit.

Answer 4

c is the right choice

One way to approach the problem is to directly use Kepler's third law of planetary motion which is mathematically

T^2 = c*r^3
where t-time period
c - some constant
r - radius of the orbit

you can also directly derive the above result using gravitational force canceling the centripetal force. The mass of the object does not affect this at all.

Answer 5

C...The planet nearerst the sun, Mercury.

Answer 6

Are you asking about planet rotation of the time it takes to rotate around the sun?

Answer 7

it would be D because although its going roughly the same speed as the rest orbitally, its covering a greater distance.

Answer 8

I'm inclined to guess C.

Answer 9

c. Which happens to be Mercury.

Answer 10

c
