How are most planets and moon in the solar system alike?Select one:Most have about the same mass.Most revolve at about the same speed.Most rotate in a counterclockwise direction.Most rotate at about the same speed.

How are the revolutions of the Moon and Earth alike?Select one:Both orbits are the same size.Both are produced by gravity.Both are revolutions around the Sun.Both take the same amount of time.

Which of the planets in the Solar System has the most moons?SaturnUranusNeptuneJupiter2Gravity provides the centripetal force which causes the Moon to orbit the Earth.  In which direction does this centripetal force act?In the same direction in which the Moon is moving at a given point in timeOpposite to the direction in which the Moon is moving at a given point in timeFrom the Moon to the EarthFrom the Earth to the Moon3A satellite is in a stable circular orbit around the Earth.  A small rocket on board the satellite is used to increase its orbital speed.  What effect will this have on the satellite?It impossible to say how it will affect the radius of its orbit without knowing the initial orbital radius and mass of the satelliteIt will cause the radius of its orbit to increaseIt will cause the radius of its orbit to decreaseIt will have no effect on the radius of its orbit4Mercury is approximately 58 million kilometres from the Sun, and has an orbital period of 88 days.  Calculate the speed at which it orbits the Sun.47.93 km/s7.63 km/s0.82 km/s4.14 km/s

The jovian (giant) planetsGroup of answer choiceshave satellite systems with less than 4 moons.are all much more dense than any of the terrestrials planets.all have rings around their equators.all spin slower than the earth.all lie less than 5 AU from the Sun.

Compare Mars with Mercury and the Moon in terms of overall properties. What are the main similarities and differences?

Which explains why most objects orbit the Sun in the same direction?Select one:Earth rotates from west to east.The objects are pulled by gravity.The Sun contains most ò the matter in the solar system.The solar system formed from a spinning cloud.
