A diameter is a linear measurement that needs units. However, assuming that the units are kilometers, the Earth is about 12,700 kilometers in diameter. Venus is a little smaller at 12,100 kilometres.

In about 5 billion years at the end of its lifetime the Sun will end up as a white dwarf having about the same mass but reduced to about 15000 km in diameter What will be its density?
If the diameter is 15,000 km = 15,000,000 meters -> radius = 7,500,000 meters Volume -> 4*pi*r3/3 = 1.77×1021 m3 Mass of the Sun = 1.9891×1030 Density=M/V=1.9891×1030 / 1.77×1021 = 1,123,785,310.7 kg/m3
What depth from surface of earth is value of acceleration due to gravity one fourth the value at the earth surface?
The force of gravity is proportional to the masses of the two objects and inversely proportional to the square of the distance between them. As a result, a gravity of one fourth that on the surface of the Earth would be observable at an altitude equal to the radius of the Earth, i.e. 6400 km. Note: This is up, in the air, not down, into the Earth. This distance is in outer space.In the other direction, the force of gravity gets smaller as one goes deeper into the earth. This is because the mass outside your current radius (as you descend) does not contribute. The mass inside your current radius is proportional to the cube of the radius. Gravity is proportional to this mass divided by the square of the radius. Therefore, gravity decreases linearly with the radius. So the acceleration of gravity is equal to one fourth its value at the earth's surface at one fourth of the earth's radius, or a depth of approximately 4800 km.
How many seconds would it take to travel to the sun if you traveled at the speed of light when the radius of the earth is 6371 km equals 3960 mi?
It would take about 496 seconds to travel to the sun at the speed of light.
How fast does a spot of laser sweep across clouds of a turntable at the top of a mountain and turns 10 revolutions per second if it reaches clouds 10km away?
In km/ seconds: 10km=r= radius Circumference = 2(Pi)(r) = 20km(Pi) = 62.83185307 The laser is making 10 sweeps/ second so times the answer by ten. 200(Pi) km/sec or 628.3185307 km/sec *If you have to go by sig. figs. 600 km/sec. If you don;t know what sig. figs. are ignore this.
What is the weight of the entire earth?
At the center of the earth, your weight would measure zero on a scale.That is because the mass of the earth is evenly distributed all around you pulling you equally in all directions.You would have the same mass as on the surface (assuming you didn't burn up from the hot hot hotness down there) but you would weigh 0. Weight is the measurement of gravity's effect on a mass.
How many earths could fit between earth and the sun?
The Earths Equatorial diameter is 12756 km, and there are (on average) 149,597,890 km to the sun, so we are talking about 11728 Earths.
How many Mars equal one Earth?
Mars is 5962 km in diameter smaller than Earth, which is 12756 km in diameter. Mars is 6794 km in diameter. So 12756 km - 6794 km = 5962 km.
How large is Mars and were is it located?
Mars is 6792 km in diameter at the equator, while the Earth is 12756 km in diameter at the equator. The Diameter of Mars is around 53% of Earths. Mars is the fourth planet from the sun, orbiting at a distance of 227,936,640 km (141,633,263 miles) from the sun on average.
How many times does the earth fit in the sun?
The Earths Equatorial diameter is 12756 km, and there are (on average) 149,597,890 km to the sun, so we are talking about 11728 Earths.
What is the radius and diameter of venus?
Radius = approx 6050 km, so diameter = 12100 km.
What is Europa's diameter compared to earth?
Europa: 1561 km radius Earth: 6371 km radius The diameter is twice the radius.
Of the four planets closest to the sun which is the largest?
With a diameter of 12756 km, Earth is the largest of the four inner planets. Venus is the next largest inner planet after the Earth with a diameter of 12104 km.
What is Earth's diameter compared to Mars'?
The diameter of Mars is just over half the diameter of Earth.To be accurate, it depends on where you measure it.The equatorial radius of Mars is 3,396.2 km which is 0.533 Earth's 6,378.1 km.The polar radius of Mars is 3,376.2 km which is 0.531 Earth's 6,356.8 km.
What is the diameter of Mercury compared to the earths diameter?
Mercury's diameter is about 3032 miles (4879 km), which is about three-eighths of Earth's diameter (about 38%).Earths volume is around 17.86 times that of Mercury's volume.Earth's radius is 2.61 times that of Mercury and 18.18 times the mass.
What is the radius of a circle that has a diameter of 48 km?
radius = 48/2 = 24 km
A circle with a radius of 8 km?
Then it will have a diameter of 16 km
