WebJan 21, 2024 · Earth's distance from the sun averages to about 93 million miles (150 million km), which scientists also call one astronomical unit (1 AU). WebMars has an orbit with a semimajor axis of 1.524 astronomical units (228 million km), and an eccentricity of 0.0934. The planet orbits the Sun in 687 days and travels 9.55 AU in doing so, making the average orbital speed 24 km/s.. The eccentricity is greater than that of every other planet except Mercury, and this causes a large difference between the aphelion and … profit stewards

WebThe resulting measurement came to be around 7.23 m/s^2. This pull allows the planet to maintain its size without ruining the atmosphere. Now I know the radius, mass, and gravitational pull of Nirn: Radius: 6371 km (1 Earth) Mass: 4.4E+24 kg (0.737 Earth) Gravitational Pull: 7.23 m/s^2. WebFeb 13, 2024 · a³ / T² = 4 × π²/ [G × (M + m)] = constant. As you can see, the more accurate version of Kepler's third law of planetary motion also requires the mass, m, of the orbiting planet. To picture how small this correction is, compare, for example, the mass of the Sun M = 1.989×10³⁰ kg with the mass of the Earth m = 5.972×10²⁴ kg.
