The objects all have the correct scale - but the Sun is in the wrong place (hopefully, this is obvious). The Earth and moon are the correct distance apart relative to their size.

Let's say we want to build a model of the sun and Earth alone. Earth has a radius of about 6,371 kilometers (3,959 miles), but let's represent this with a marble 1 centimeter in diameter.

We see some of our hottest temps when Earth is furthest from the Sun (aphelion) and coolest at the closest to the Sun ...

If we ignore the Earth's motion, we find that the Sun moves relative to the CMB at 368 ± 2 km/s, and that when you throw in the motion of the local group, you get that all of it — the Milky Way ...

It is 4,892 light years from Earth and has a circumference of 5.46billion miles - around 2,000 times that of our sun. It would take a passenger jet 1,100 years to fly round it once.

With a long enough lever and a place to stand, Archimedes knew he could move the Earth. Similarly, weighing massive objects like planets and stars on a balance scale as one might with a pound of ...

The sun has a galactic-scale orbit. The sun rotates, though not quite the same way as a terrestrial planet like Earth. Like the gas and ice giants, the sun’s equator and poles complete their ...

At aphelion, Earth’s distance from the sun is about 94.5 million miles. Six months later, at the start of January in the winter, Earth is at its closest point to the sun at 91.5 million miles ...

On Monday, November 11, Mercury will pass in front of the Sun as seen from Earth. It is known as a transit. It last happened in 2016, but the next one won't happen again until 2032. Catch it if ...
