The sun has a volume of 1.41 x 1018 km3, whereas the Earth has a volume of 1.08 x 1012 km3. It is estimated that around 1.3 million Earths may be contained within the sun’s volume when the volume of the sun is divided by the volume of the Earth. This, on the other hand, presupposes that the Earths are squeezed together so that there is no vacant space between them.
How many Earths can you cram into the Sun’s interior?
- The Sun is huge enough that around 1.3 million Earths could fit within (if they were crushed in), or 960,000 Earths could fit if they preserved their spherical shape.

Is the sun 3 times the size of Earth?
The Short Answer: Our Sun is a brilliant, hot ball of hydrogen and helium that sits at the core of our solar system, radiating energy into space. It has a diameter of 864,000 miles (1,392,000 km), which makes it 109 times broader than the Earth in diameter.
Will the Earth ever run into the sun?
By that time, all life on the planet will have been exterminated. Most likely, the planet will be absorbed by the Sun in around 7.5 billion years, once the star has entered the red giant phase and grown beyond the planet’s present orbit, according to current estimates.
Is the sun getting bigger?
Since its inception around 4.5 billion years ago, the Sun’s size has expanded by approximately 20% on average. It will continue to grow at a moderate rate until perhaps 5 or 6 billion years from now, when it will begin to change at a significantly quicker rate.
Is our sun yellow or white?
When the sun shines, it is a brilliant white. The sun emits all of the hues of the rainbow more or less uniformly, and this combination is referred to as “white” in physics. Under the lighting of sunshine, this is why we can perceive such a wide variety of colors in the natural world.
Is Earth going to crash into another planet?
As a result of the chaotic development of planetary orbits in the solar system, a near encounter or perhaps a collision between Mars and the Earth is possible in fewer than 5 billion years, but the chances of this happening are extremely remote.
Will the moon crash into Earth?
“Extremely improbable,” says the author. To throw the Moon off its orbit, however, a large enough object would have to impact the Moon at the appropriate speed and at the right angle, according to Byrne, in order for it to succeed. Consequently, the Moon’s orbit is growing farther away from Earth rather than closer, and the Moon is not on a collision path with our planet.
What year will the Sun explode?
Scientists have undertaken a great deal of research and study, and they have come to the conclusion that the Sun will not erupt for another 5 to 7 billion years. When the Sun inevitably ceases to exist, it will first grow in size as it consumes all of the hydrogen present at its core, and then gradually contract in size until it is reduced to the size of a dying star.
What would happen if the Sun died?
When the Sun’s hydrogen reserves are depleted, it will erupt into a red giant, which will consume Venus and Mercury in the process. The Earth will be reduced to a burnt, dead rock, having lost its atmosphere and had its seas cooked away. There is a lot that can happen in the next 5 billion years, even if the Sun will not become a red giant for another 5 billion years.
Can anything survive the Sun?
In fact, there is no substance on the face of the planet that could sustain this kind of heat. The finest we’ve got is a compound called tantalum carbide, which can withstand temperatures up to 4,000 degrees Celsius at its most extreme temperature. On Earth, it is used to coat the blades of jet engines. So even if we made it this far, we wouldn’t be able to survive in this environment.
Why is the sky blue?
Small air molecules scatter white light as it travels through our atmosphere, causing it to seem to “scatter.” Known as Rayleigh scattering, the scattering induced by these small air molecules grows in intensity in proportion to the wavelength of light being employed. As a result, blue light is dispersed more than red light, and the sky appears bluer during the day than at night.
Is the sun black?
The sun, like all matter, emits a “black body spectrum,” which is characterized by the temperature at which it is at its surface. It is the continuum of radiation at many various wavelengths that is emitted by any body with a temperature greater than absolute zero that is referred to as a black body spectrum. As a result, the sun seems to be blue-green in color.
Why is the ocean blue?
The ocean appears blue because water absorbs colors that are found in the red portion of the spectrum of light. This acts as a filter, allowing us to see colors in the blue portion of the light spectrum that were previously hidden. Due to the reflection of light off of floating sediments and particles in the water, the ocean may also appear to be tinted green, red, or other colors.
