In the outermost regions of the solar system, astronomers have made a rare, spectacular discovery. They observed an as yet unknown dwarf planet, which is three times as far from the sun as Pluto. The small celestial body is named 2014 UZ224, but DeeDee is named after the English distant dwarf - distant dwarf in Dutch.

The solar system is pretty well organized, but the starting point was chaotic. On the outside, where it was coldest, comets of dust and ice were formed. In the inner solar system it was so hot that water and volatile matter could not exist. The earth and the other inner planets consisted mainly of silicates and metals.
60 years ago, the Polish astronomer Kazimierz Kordylewski claimed that he had seen concentrations of dust in orbit. These dust moons had not been observed since then - until now. Hungarian astronomers have rediscovered one with special filters on their telescopes, which, like the moon at 400.
When James Cook sets sail for Tahiti in August 1768, he is essentially on his way to a strange planet. Not only does he lack the means of communication and reliable cards, he also relies on Venus. In addition, Captain Cook has a tough deadline. His expedition from England must be on the distant Pacific island before June 1769, otherwise he cannot see the neighboring planet of the earth passing like a black dot along the sun.
About Saturn The second largest planet of the solar system, Saturn, is now aligned with the earth and the sun. This means that it is relatively close to the earth (but still more than 1 billion kilometers away), and that the side facing us is bathed in sunlight. Because of those two factors you now have the best chance of the year to take a good look at Saturn.
Radio signals measure distance Astronomers have calculated their distance from the sun on the basis of the orbit of planets, and can also use sensors to determine the distance to small objects in the corners of the solar system. Earlier this year, the New Horizons probe passed the furthest object in the solar system, the ice sphere Ultima Thule.
Uranus is a gaseous planet with no solid surface. Just like Neptune, it has a different composition than Jupiter and Saturn. That is why Uranus and Neptune are also known as the 'ice giants'. Here we have collected ten facts about the seventh planet of our solar system. 1. What does Uranus consist of?
In the coldest regions of the solar system, past Neptune, billions of celestial bodies fly around in the area that we call the Kuiper Belt. According to estimates, the Kuiper Belt extends over 4.5 billion kilometers and has hundreds of thousands of objects with a diameter of at least 100 kilometers.
1. Borealis Basin, Mars Diameter of 9200 km. The Borealis Basin covers the entire northern hemisphere of Mars. In this area the crust of the planet is different, indicating a powerful impact of a large celestial body with approximately 2% of the mass of Mars. MOLA Science Team / NASA 2. Utopia, Mars 3300 km diameter.
The planet Venus Venus is sometimes called the sister planet of the earth, but that only applies to the size and mass of the planet. On the surface, Venus is a glowing hot pressure cooker. Venus is a rock planet and therefore has a solid surface, just like the earth. It is on average about 460 ° C hot on Venus, making it the warmest planet in the solar system.
Temperature of planets measured via radiation Astronomers measure the temperature of a planet via the radiation it emits. Cold planets emit infrared radiation with long waves, the warm with short waves. Astronomers compare radiation Astronomers calculate the power of the planet's infrared radiation by comparing the reflected radiation of the planet with the radiation from the sun in the infrared region.
What do you do if your name is Google and you have already charted almost the entire earth? Then you seek your salvation on the other planets and moons of the solar system. This is evident from the latest update that the American internet giant has released for the map service Google Maps. Now you can not only look for the shortest route from home to work, but also take a look at the glowing hot surface of Venus, the kilometer-thick ice layer of Enceladus or the huge crater on Mimas.
The planet Neptune The planet Neptune is a gas planet and it is the outer planet of the solar system. Neptune consists mainly of gas, has no solid surface and is, like neighboring planet Uranus, an ice giant. Neptunus also looks a lot like its largest neighbor planet. The planet has no solid surface, but consists primarily of the hydrogen and helium gases.
The surface is gas, huge storms are raging and the sound could come from a horror movie. In his journey around the largest planet of the solar system, Juno not only took pictures of Jupiteren's moons. The probe also has other measuring instruments on board, and has recorded the sound of the huge gas planet, among other things.
At the top of Saturn, there is a hexagonal cloud pattern around the North Pole with a hurricane in the center. The hexagon is striking in itself because of its clear hexagonal shape and its diameter of up to 32,000 kilometers. And now it appears that the hexagonal cloud cover has even more surprises in store and behaves like a chameleon: it has faded in color.
The planet Saturn Saturn is the second largest gas planet in the outer solar system. The planet is known for the beautiful rings that surround it. Saturn is a gas planet and therefore has no solid surface. It consists mainly of hydrogen and helium, but may have a core of iron, nickel and various rocks.
1. Red storm on Jupiter is full of water © NASA / JPL-Caltech Astrophysicists have investigated the clouds in the big red spot - a storm - that has been hanging over Jupiter for at least 150 years. They now suspect that these clouds are full of liquid water. That is why they also want to map the water on the rest of the planet.
A huge precision maneuver is when the New Horizons probe on New Year's Day at 6:33 am our time flies right past the only 30-kilometer-long ice sphere Ultima Thule in the border region of the solar system: the Kuiper belt. From a distance of only 3500 ki-lo-meters, the probe will, among other things, make close-ups of the soil and collect dust samples.
What colors would you see if you were to ride along with the Cassini spacecraft, which flew closer to Saturn than any vessel has ever done? That is now known. By combining images with different color filters, a truthful image was created of the view that the space probe had when it came very close to the gas giant.
Astronomers have found new evidence for the theory that there is an enigmatic giant in the outer solar system: a huge block of rocks that pulls all the planets around us. NASA has released a press release in which the space agency claims to provide compelling evidence for the existence of a ninth planet.
In the days around April 7, you have a unique opportunity to study Saturn, the second largest planet in the solar system. At that time, the distance between the earth and Saturn is only 1.2 billion kilometers. Seen with the naked eye, Saturn looks like a bright, yellowish star, but with ordinary binoculars that are 30 times larger, you can already see that the planet has a slightly elongated shape.
