What else can I help you with?
Planets that are smallest to the sun revolve at a faster speed?
Yes, planets that are closer to the Sun, like Mercury and Venus, revolve at faster orbital speeds due to stronger gravitational attraction from the Sun. According to Kepler's laws of planetary motion, the closer a planet is to the Sun, the shorter its orbital period, meaning it takes less time to complete one orbit. This is why Mercury, the smallest and closest planet to the Sun, has the highest orbital speed.
Which of the planets orbital time is 7 times smaller than that of Uranus?
Jupiter's orbital period is only 1.53% less than1/7 the orbital period of Uranus.
Uranus has a bigger or less speed than Jupiter?
Uranus has a lower orbital speed than Jupiter.
How do the orbital inclinations of the inner planets compare with those of the outer ones?
The inner planets (Mercury, Venus, Earth, and Mars) have relatively low orbital inclinations compared to the outer planets (Jupiter, Saturn, Uranus, and Neptune). The inner planets orbit the Sun in a more or less flat plane known as the ecliptic, while the outer planets have more inclined orbits relative to this plane.
What is Venus' path?
Venus' orbital path is the most circular of all the planets. The eccentricity of the orbit of Venus is less than 0.01.
How does the orbit of each planet depends on its distance from the sun?
The square of the time period of revolution is directly proportional to the cube of the mean distance between the planet and its Sun. T2 α R3T = Time Period R = Length of the semi-major axis
What s Mercury's objects in its orbital path?
Mercury's orbital path primarily contains small debris and dust particles, as it is the innermost planet in the solar system. Due to its proximity to the Sun, it has a relatively clean orbital environment compared to other planets. However, it may also encounter meteoroids and small asteroids that occasionally cross its path. Overall, Mercury's orbital path is less cluttered than those of the outer planets.
Is Uranus' speed less than or greater than Jupiter's speed?
Less. Uranus is further away from the Sun. In general, the planets closer to the Sun move faster.
Orbital speed is the speed with which a planet moves around the Sun This speed is determined by?
The mass of the Sun and the distance between the planet and Sun. As the Sun's mass is (more or less) constant, all we need to know is the distance. Technically this is called the "semi major axis" of the elliptical orbit. (If you wanted to be really, really accurate the mass of the planet does have a very very small effect.)
Why does venus take 225 days to revolve around the sun and earth takes 365 days?
Because Venus has less distance to travel than the Earth and is travelling faster. With an orbital speed of 35.02 km/s and an orbital period of 224.70069 days gives an orbital distance of 679,883,169.35km The Earth has an orbital speed of 29.78 km/s (Slower than Venus) and an orbital period of 365.256 days gives an orbital distance of 939,800,765.95km
Does the speed of light change on different planets?
The speed of light in empty space is constant, i.e., always the same. However, the speed of light in another medium can change. So, if a planet has a denser atmosphere than Earth, the speed of light will probably be slightly less than here.
How does the mass of a planet relate to its distance from the sun?
There is no necessary connection between mass and distance. The mass of a planet does not affect its orbital speed, for example. However the "giant planets" are further from the Sun than the less massive "terrestrial planets". The outer (more massive planets) contain a lot of gases. So, they would surely lose a lot of their mass if they were nearer the Sun. (In fact, we have found planets called "hot Jupiters" orbiting other stars. These are Jupiter type planets, but they orbit very close to their star.)
