The first man made object sent into space was in 1957 when the Russian satellite named Sputnik was launched. While the solar eclipses are rare, they still occur at least once every 18 months. If we are to scale back from these ridiculous vast galactic distances and numbers, we will find a cozy little system with a little yellow Sun smack dab in the middle of it. It is more than 1,708 times the size of the Sun. Milky Way is our home galaxy. Links out; SCaN Kids Zone. Each of the outer planets has rings around it, but only the Saturn’s’ are visible to us from Earth. 56.

These planets together make up 99% of the mass that is orbiting the Sun. Even though there are over a million asteroids estimated in the belt, they populate such a huge area of space that the distances between individual asteroids are at least several kilometers. The hottest planet in our solar system is 450° C. It has a radius of 36,184 miles (58,232 km) – nine times that of Earth. Jupiter has 67 natural satellites (or moons), the highest number of all the planets in the solar system. The nucleus of a comet is usually not bigger than 10 km, but as the comet approaches the Sun and the frozen gases begin to evaporate, the nucleus can expand to over 80 000km. Jupiter has a huge perpetual storm that rages in its upper layers, known as the Great Red Spot. Did you know giant, spinning storms on Neptune are big enough to swallow the whole Earth?

When you crack a whip, it makes a sharp sound because the tip of the whip is traveling faster than the speed of sound. The first person to look into space with a telescope was Galileo, nearly 400 years ago. Eclipses are basically cosmological miracles. Space Science Facts. The Hubble classification is a bit more complex – Elipticals, spirals, lenticulars and irregulars, of which each category has subcategories. General Science. If one was to drive a car on one of the Saturn’s rings, at the speed of 100 km/h, it would take over 14 weeks to finish one lap. 12. 20. The only natural satellite that orbits the Earth is Moon. Universe is estimated to be 13.82 billion years old. Jupiter is the biggest planet in our system, over 300 times bigger than Earth. A few years ago I helped a local school put together a space science day. It has much weaker gravity than Earth: with the gravity of 38%, a 100 kg person would weight only 38kg on Mars! Contrary to the movies and popular belief, the asteroid belt is fairly easy to maneuver in a spacecraft. However, this list is much too short; keep it growing by adding your own science facts in the comments section.

That is because Venus has an extremely dense carbon-dioxide atmosphere, which creates the strongest green-house effect known to man. It is a sort of mini sonic boom! The universe is crazy enough that it really doesn’t need our help in that department. The reason why we feel it’s much rarer than that is because they can be seen only from a fairly small area on the Earth. There is no dark side of the Moon.
