You can determine the mass of any planet by astronomically determining the planet's orbital radius and period. Then calculate the required centripetal force and equate this force to the force predicted by the law of universal gravitation using the sun's mass

Does earths mass determine its location in the solar system?

No. A planet's mass does not determine the position of its orbit.


Why is it necessary to know the distance to a planet in order to determine the planet's mass?

There is something missing from the question. The planet must have a moon. The only way to measure the mass of a planet is by using data about a moon orbiting the planet or data about the path of a spacecraft passing or going into orbit around the planet. If you know the distance to a planet then you can work out the moon's distance from the planet. The planet's mass can then be found. It's a bit of trigonometry and Newton's version of Kepler's Third Law. So that's the reason that it is necessary to know the distance to the planet.


Is it possible to determine the planet's mass from a star's velocity curve?

Yes, it is possible to determine a planet's mass using the star's velocity curve caused by the planet's gravitational pull. The mass of the planet can be calculated by analyzing the changes in the star's velocity as it orbits due to the gravitational interaction with the planet. This can provide valuable information about the planet's characteristics and orbital dynamics.


What is the mass of planet x?

In order to calculate that figure, we need to know the mass of planet x and the radius of its surface. These are particularly difficult to measure in the case of planet x, primarily because it doesn't exist.


A planet's density can be measured by combining?

the planet's mass and volume using the formula density = mass / volume. By measuring these properties, scientists can determine the density of a planet, which gives insights into its composition and internal structure.


How big will a planet be if it is located far from the sun?

The size of a planet is not related to it's distance from the sun. Planet mass and orbital velocity are factors that determine it's distance from the sun.


If you know the size of an asteroid you can determine its density by?

determining its mass from its gravitational pull on a spacecraft, satellite, or planet.


What characteristic of a planet determine the strength of its gravitational force on other objects?

The mass of the planet is all you need to know. That, along with the mass of the other object and the distance between their centers, tells you the strength of the force between them.


Why is it important to know the distance to a planet in order to to discover the planet's mass?

Please ignore this question. I was just using this to search for a previous similar question. It was not intended to be a "real" question. Sorry, I submitted it by mistake! I found the question and "improved" the answer. In case you are curious it was: Why is it necessary to know the distance to a planet in order to determine the planet's mass?


Does the planet your on determine your mass or weight?

Your mass remains constant regardless of the planet you are on, as it is determined by the amount of matter in your body. However, your weight, which is the force of gravity acting on your mass, varies depending on the gravitational pull of the planet.


What is the formula for density of a planet?

Density of a planet = (Planet's mass) divided by (Planet's volume)


Which planet is closest in mass to the size of planet Earth?

Venus is the planet closest in mass to Earth, with a mass about 81% that of Earth.
