How do the masses of Jovian planets compare to the masses of terrestrial planets?
The density of terrestrial planets is greater than that of rock, reflecting the presence of extremely dense metal cores. (2) The Jovian planets are made primarily of hydrogen and helium. The Jovian planets are: high in mass (> 14 Earth masses) low in density (< 1700 kg/m3).
Why do the inner planets have less mass than the outer planets?
This is because the outer planets are in a gaseous state while the inner planets are solid and more compact. Consequently, the density of the inner planets is greater than that of the outer planets. Despite the density differences, the mass is smaller for the inner planets than the outer planets.
How does the mass of the Sun affect the orbit of all the planets?
That is, the acceleration of a planet in its orbit around the Sun depends upon the mass of the Sun and the inverse square of the planet’s distance from the Sun. As the planet moves further away in its orbit around the Sun, the gravitational force exerted by the Sun on the planet decreases.
How could we determine the mass of a planet such as Venus which has no moon?
The only way we can measure a planet’s mass is through its gravity. Mercury and Venus have no moons, so their exact masses were not known until a few decades ago. Before space flight was developed, the only way to measure their gravity was to see how they affect other planets’ orbits.
How did the formation of Jovian planets differ from the formation of terrestrial planets?
How did the formation of Jovian planets differ from the formation of terrestrial planets? The Jovian planetesimals were larger than those that made terrestrial planets. The Jovian planetesimals became large enough to gravitationally capture hydrogen and helium from the nebula.
How was the formation of Jovian planets similar to that of the terrestrial planets How was it different?
Answer:Similar-The formation was similar due to accretion which is the process of small solid rock”seed” as they grew into planets and once the gases came from a solid material. Different- As each jovian planet is wrapped around it own disk of gas but terrestrials don’t have this.
How do the distances between the inner planets compare to the outer planets?
There is no difference between the distances of the orbits of the inner planets and the outer planets. The planets are all equally distanced from each other.
Why are inner planets different than outer planets?
Inner Planets vs Outer Planets The difference between the Inner Planets and Outer Planets is that the Inner Planets are close to the Sun, smaller and rockier whereas the Outer Planets are further away from the Sun, large and mostly made up of gases.
What is the mass of the sun compared to the solar system?
The mass of the sun is 1.989 x 1030 kilograms, about 333,000 times the mass of the Earth. The sun contains 99.8 percent of the mass of the entire solar system, leading astronomers Imke de Pater and Jack J. Lissauer, authors of the textbook “Planetary Sciences,” to refer to the solar system as “the sun plus some debris.
How did changing the mass of the sun affect Earth’s orbit?
Essentially, an increase in mass means an increase in gravity, while a decrease in mass means a decrease in gravity. then its gravitational pull on Earth would lessen as well, ultimately changing the very nature of our orbit around the Sun.
How do we calculate the mass of planets?
The masses of the planets are calculated most accurately from Newton’s law of gravity, a = (G*M)/(r2), which can be used to calculate how much gravitational acceleration (a) a planet of mass M will produce on objects at distance r away.
How do we estimate the mass of the Earth?
The mass of the Earth may be determined using Newton’s law of gravitation. It is given as the force (F), which is equal to the Gravitational constant multiplied by the mass of the planet and the mass of the object, divided by the square of the radius of the planet.
What are the different masses of the planets?
What are the Different Masses of the Planets? It is a well known fact that the planets of the Solar System vary considerably in terms of size. For instance, the planets of the inner Solar System are smaller and denser than the gas/ice giants of the outer Solar System. And in some cases, planets can actually be smaller than the largest moons.
How many moons are there in the inner Solar System?
Moons of the Inner Solar System. Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons. In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have numerous moons.
Which of the following planets has no moons?
Of the terrestrial (rocky) planets of the inner solar system, neither. Mercury nor Venus has any moons at all, Earth has one, and Mars has its two small moons. In the outer solar system, the gas giants (Jupiter, Saturn) and the ice giants (Uranus and Neptune) have numerous moons.
Why do some planets have so many moons?
In the outer solar system, the gas giants (Jupiter, Saturn) and the ice giants (Uranus and Neptune) have numerous moons. As these huge planets grew in the early solar system, they were able to capture objects with their large gravitational fields.
