Which statements describing orbits are correct? Select three.

For a stable orbit, the radius must change if the speed changes., Gravity allows planets and satellites to maintain this type of orbit., Gravity can cause changes in velocity but not in speed for circular orbits.

an object with a very elliptical orbit around the Sun.

an orbiting body much smaller than the eight planets.

Identify the correct statements about our solar system. Select three.

The further away a planet is from the Sun, the longer its orbital duration., Planets that are further from the Sun have lower surface temperatures., The bigger the planet's mass, the bigger it's gravitational field strength.
