What if two planets were in the same orbit?
If two planets pass closely by one another in orbit, one can perturb the other, resulting in a massive orbital change. These two planets could collide, one of them could get ejected, or one could even get hurled into their central star.
Do objects fall at the same speed on different planets?
Take two objects of different masses, like a golf ball and a bowling ball. On any given planet (or moon), those two will both fall at the same speed (determined by the gravitational field strength of the planet/moon).
What two planets have the same mass?
Mass stays the same regardless of location and gravity. You would have the same mass on Mars or Jupiter as you do here on Earth. Your weight is different on other planets due to gravity. However, your mass is the same everywhere!
How does a planet’s mass affect its orbit?
A planet’s mass has no effect on its orbit around the Sun. More massive planets must have more circular orbits. A more massive planet must have a larger semimajor axis. More massive planets orbit the Sun at higher average speed.
Can two planets follow the same orbit?
So, strictly speaking, two ‘planets’ in the same orbit would not be classed as planets. But it is possible for two planet-like bodies to share the same orbit around a central star without colliding: the second object would need to be positioned at a particular point in the first object’s gravitational field.
Between which two planets does the orbit of the series lie?
As you can see in Table 1, the asteroid belt (represented by its largest member, Ceres) is in the middle of a gap between the orbits of Mars and Jupiter. It is because these two planets are so far apart that stable orbits of small bodies can exist in the region between them.
How is it possible for two objects having different size and mass fall at the same rate when dropped at a certain height?
Because Earth gives everything the exact same acceleration, objects with different masses will still hit the ground at the same time if they are dropped from the same height.
Will 2 objects of different weight fall at the same speed?
Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity. Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.
Which two planets are most similar to each other?
In composition, size, in atmosphere, etc? Venus and Mars are the most like Earth, but in different ways. In terms of size, average density, mass, and surface gravity, Venus is very similar to Earth. But Mars is the planet that is most similar to Earth in other ways.
What two planets are closest to each other?
Mercury (above) is the closest planet to Earth — in fact, it’s the closest planet to every other planet. This is startling because we all have a built-in misconception about the layout of the solar system. It’s true that Venus orbits the sun between Earth and Mercury.
Does the mass of the planets affect their orbit period?
Assuming we are talking about the mass of the satellite (and not the mass of the body being orbited), mass does not affect the orbital speed.
How does a planet’s mass affect its orbit around the sun quizlet?
A planet’s mass has no effect on its orbit around the Sun. More massive planets must have more circular orbits. A more massive planet must have a larger semimajor axis.
Do two planets with the same mass have the same gravity?
By this definition, a very sensible, useful, one, two objects with the same mass, whatever their density will bend space to the same degree and so gravity is the same. However, if two planets have the same mass but one is less dense than the other, the less dense one must be bigger.
What would happen if two planets in our solar system collide?
If two planets pass closely by one another in orbit, one can perturb the other, resulting in a massive orbital change. These two planets could collide, one of them could get ejected, or one could even get hurled into their central star.
What happens if one planet is larger than another?
If one planet is larger (In size) than another, its surface gravity _____. Might or might not be bigger, depending on its density. Astronauts sometimes train in water tanks because the buoyancy of water exerts a force that opposes the pull of the Earth’s gravity.
What happens when two massive bodies orbit each other equally?
When one object is very massive compared to the other object, the center of the balance point of the orbit can be inside the massive object. Two equally massive bodies orbit each other equally. (You can show that the accelerations that are equal by equating the force of gravity formula to F = m X a for each object.)
