Ceres was discovered by Giuseppe Piazzi at the Academy of Palermo, Sicily on 1 January 1801, which was half a century before the discovery of Neptune. It was the first object to be seen in the asteroid belt and was listed as one of the solar system planets for over 50 years. However a...
Lined up like familiar faces in your high school yearbook, here are images of the 33 largest objects in the Solar System, ordered in size by mean radius. Engineer Radu Stoicescu put this great graphic together, using the highest resolution images available for each body. Nine of these object...
When one thinks of the solar system, he has usually in mind the picture based on the solution of the two-body problem approximation presented by Newton, namely the ordered clockwork motion of planets on fixed, non-intersecting orbits around the Sun. However, already by the end of the 18th ...
pointing towards Hadar and Alpha Centauri, the closest star to the solar system. Within minutes of us arriving, we could see the Milky Way, which got brighter and brighter as our eyes adjusted to the dark.
A solar mass refers to the standard unit used to measure the mass of stars, equivalent to the mass of the Sun. It can be determined accurately by observing the orbital periods and distances of planets in our solar system or by applying Kepler's third law in binary star systems. ...
Like all the planets in our solar system, Earth and Mars go around the sun. But Earth is closer to the sun, and therefore revolves along its orbit(轨道) quickly. Earth makes two trips around the Sun in about the same amount of time that Mars takes to make one trip. So sometimes the...
A scale diagram of the orbits of the eight planets in our solar system. If we have done our calculations correct, the scale is approximately 16,345,000,000,000:1 (so one centimetre on an adult t-shirt will be roughly equivalent to slightly more than 163 million km). The sun, by comp...

Aliphatic-rich organics might have formed from precursor molecules either in the protoplanetary disk, or interstellar medium before the Solar System formed24 and were then slightly modified during aqueous alteration in the Ryugu (grand)parent body. The size (<1.0 km) of Ryugu is too small to...
