  • How Big is the Earth? | Size Comparison, Actual Size Facts
    Earth’s Moon has a diameter of around 3 474 km 2 158 mi and a radius of 1 737 km 1 079 mi In comparison to Earth, the Moon has only 1 2% of Earth’s mass, or in another way of looking at it, the Earth is 81 times heavier than the Moon The Moon is about one quarter the size of Earth, and it would take around 50 moons to fill the Earth
  • How Many Miles Around The Earth? | Facts, Land Area, Surface Area
    If you measured the radius from Earth’s center to the equator, you would obtain a radius of 3 963 2 mi 6 378 1 km However, if you would measure it from the center to one of Earth’s polar regions, you would obtain a radius of 3 949 9 mi 6 356 8 km It isn’t such a big difference, but it is present
  • How Big is the Moon? | Comparisons, Size, Facts Information
    How big is the Moon? Our Moon has a mean radius of 1,737 kilometers 1,079 miles, while its polar radius is 1,736 km 1,078 mi, and its equatorial radius is 1,738 km 1,079 mi The Moon’s diameter is 3,474 km 2,158 mi, and it is the biggest Moon in the Solar System relative to the size of its planet
  • Earth Facts | Surface, Atmosphere, Satellites, History Definition
    The sphere of gravitational influence, of the Earth, is about 1 5 million km (930,000 mi) in radius This is the maximum distance at which the Earth's gravitational influence is stronger than the more distant Sun and planets Objects must orbit the Earth within this radius, or they can become unbound by the gravitational perturbation of the Sun
  • How Big is the Sun? | Comparisons, What Is Bigger, Facts
    The most giant planet in our Solar System, namely Jupiter, has a diameter of around 142 984 km 88 846 mi at the equator, and a diameter of about 133 708 km 83 082 mi at the poles It has a mean radius of 69 911 km 43 440 mi, and its mass is equivalent to 318 Earth masses You could fit 1 300 Earths inside Jupiter
  • How Big is Jupiter? | Size Comparison, Actual Size Facts
    So how big is Jupiter actually? Well, Jupiter has a diameter of around 142 984 km 88 846 mi at the equator, and a diameter of about 133 708 km 83 082 mi at the poles It has a mean radius of 69 911 km 43 440 mi, and its mass is equivalent to 318 Earth masses Jupiter has more than 11 times the diameter of Earth

  • How Far is the Sun From Earth? | Distance, KM, Time Takes Facts
    When this happens, Earth will be with 750,000 km 466,028 mi farther away from the Sun; however, the Sun will also expand its radius for more than 256 times its current size (696,340 km 432,685 mi), reaching over 178 million km 110 million mi in radius, inevitably engulfing Earth in the end How Far is it From Earth to Space?
