What are the forces acting on an astronaut on the moon and on earth and on Mercury and on Venus?
You probably want to compare the gravity on the moon and on the three planets. Let's assume that you do. Call the gravity of the earth g and let's compare. Moon - 0.1654 g Mercury - 0.38 g Venus - 0.904 g What that all means is that if you weigh 100 pounds on earth, you'll weigh about 16 and 1/2 pounds on the moon, 38 pounds on Mercury, and about 90 and 1/2 pounds on Venus.
What else can I help you with?
Did the astronauts land or did they just fly by over Venus?
Astronaut did not land in Venus because the planet is hot. If the astronaut land on Venus, they will burn their selfs.
What planets have a rocky surface?
In this solar system there are four, Mercury, Venus, Earth, and Mars.
Is mercury the only planet that does not have a moon?
No. Venus does not have a moon either.
Which list is terrestrial plantes in order from smales to largest?
The terrestrial planets, in order from smallest to largest, are Mercury, Mars, Venus, and Earth. Mercury is the smallest, followed by Mars, then Venus, and Earth is the largest of the four. These planets are primarily composed of rock and metal, distinguishing them from the larger gas giants.
Which plant is farthest from earth?
Planet furthest from earth? Neptune, since Pluto is no longer considered a planet.But, if you do consider Pluto a planet, then normally, the furthest planet from Earth is Pluto, but sometimes it is Neptune. (Pluto's orbit crosses Neptune's).
Who was the first astronaut to visit Venus?
No astronaut has visited Venus yet.
Who was the first astronaut travel in venus?
Dennis Tito was the first astronaut to travel to the planet Venus.
Planet that has no moons?
The planets in our solar system that do not have any moons are Mercury and Venus.
Did the astronauts land or did they just fly by over Venus?
Astronaut did not land in Venus because the planet is hot. If the astronaut land on Venus, they will burn their selfs.
What are the the 2 planets without moons?
Mercury and Venus.
Does venus mars or mercury have tidal forces?
Phobos and Deimos are small moons of Mars, and consequently the tidal forces are extremely weak. Venus and Mercury have no moons, but are still subject to the tidal forces of the sun, and in both cases these forces are considerably larger than they are on Earth (solar tidal forces on the Earth noticeably affect sea levels). It's also worth noting that tidal forces affect the entire planet (think of a tennis ball being squeezed - in this case the squeezing is caused by the gravitational attraction of the sun).
Which planet does not have a moon?
Mercury and Venus, which makes sense because the tidal forces created by the Sun's gravity would be stronger for those two planets, which would make it difficult to capture moons. Tidal forces are created by the difference in the gravitational force between one side of a prospective orbit and the opposite side.
Which planet doesn't have a moon?
In our Solar System, Mercury and Venus have no moons.
What is in between the sun and Earth?
Mercury and venus
Name the two planets that do not have moons?
Neither Mercury nor Venus are known to have any moons.
Is Mercury the same size as Venus'?
No, Mercury is smaller than Venus in terms of size. Mercury has a diameter of about 4,880 kilometers while Venus has a diameter of about 12,104 kilometers.
Which 2 planets do not have any natural satellites?
No natural satellites of the planets Mercury or Venus have ever been discovered.
