With every year that goes by, we find ourselves just slightly — 1.5 centimeters, or 0.00000000001% the Earth-Sun distance — farther away from the Sun than the year before. The reason why is ...

How far away is Mars? The distance between Mars and Earth depends where the planets are in their orbits of the Sun. Mars, also known as the Red Planet, should be around 33.9million miles (54.6m ...

How many dwarf planets are there in our solar system? The recent discovery of 2017 OF201 makes the tally anywhere between ...

Right now, Earth is about 3.1 million miles farther from the sun than it is in early January when it reaches perihelion, its ...

Every object orbiting a single mass (like our Sun) makes an ellipse, containing a point of closest approach that's unique to that particular orbit, known as periapsis. For the past 4.5 billion years, ...

One common question people seem to have about the planets' orbits is why the planets are drifting away from the Sun, given the Sun's strong gravitational pull keeping the Solar System together ...

The Sun's outer layers will swell to more than 100 times their present diameter, but the exact details of its evolution, and how those changes will affect the orbits of the planets, still have ...

So, the tidal influence of the Sun on Uranus’ orbit is smaller by around 16 orders of magnitude (that’s a factor of 1016). The effect for Earth or even Mercury is much larger but still negligible.

With the help of a three-dimensional map of stars near the sun, astronomers can search for alien planets that might hold life. The map was created by NASA’s Chandra X-ray space telescope, which ...

The sun’s gravitational pull may be able to capture incoming objects from as far as 3.8 light years away, including interstellar comets and even rogue planets.
