What are considered a double planet?
A double planet describes two bodies of similar size and mass that are in orbit (not necessarily around each other) . The Earth and Moon would not be considered a double planet because of the great size and mass difference between the two. However, Pluto and its moon Charon COULD be classified as a double planet- both have similar sizes and mass, and orbit a point outside of one another.
How would the orbits differ if a star and planet were of similar mass to each other?
Two objects of the same mass will also move in elliptical orbits. Whether the two bodies are of the same mass or different, one focus of the elliptical orbit is the center of mass (barycenter).
Which planet has a similar mass to earth?
Venus.
The planet Venus is similar to Earth in its?
size, mass, density, and volume. Other than that, its VERY different
What are 3 reasons that Venus is called earths sister planet?
Venus is similar in size and mass to Earth, making them roughly "sister planets" in terms of their physical characteristics. Both Venus and Earth are rocky planets with similar compositions and densities. They are relatively close to each other in the solar system, with Venus being the closest planet to Earth.
Do objects on other planets weigh the same as they weigh on Earth?
No. Weight is the measure of how much force a planet pulls an object, that force is determined by the planet's mass and radius, and each planet has a different mass and radius.
What happens to your mass as you move from planet to planet?
Your mass does not change. Your weight, however, changes in proportion to the gravity of each planet.
Why are large astronomical bodies such as planet and stars around?
all parts of the planet pulled each other toward the center of the mass by gravity
If two planet's of same mass revolving around the same body at distance a and b respectively are in front of each other after how much time they are again come in front of each other?
If two planet's of same mass revolving around the other body at the distance a and b respectively bus more than a and in front of each other then after how much time they will again come in front of each other
Will your mass change from planet to planet?
No. Your mass will stay the same. Your weight, however, will change in direct proportion to each planet's gravity.
How does a planet gets its force of gravity?
A planet gets its force of gravity from its mass and the distance from its center. The more massive the planet, the stronger its gravitational pull will be. Gravity is a fundamental force of nature that attracts all objects with mass towards each other.
Does the number of moons effect the mass of a planet?
Yes, the number of moons can affect the mass of a planet to some extent, as the gravitational pull between the planet and its moons can influence each other. However, the effect is usually minimal compared to the mass of the planet itself.
