This week astronomers at Cal Tech announced that our solar system may in fact have nine planets after all, and no, it’s not about Pluto.
Using the Atacama Large Millimeter Array (ALMA) located in the Atacama desert of northern Chile, astronomers were surprised to discover evidence that could point to a massive new planet X at the edge of our own solar system.
There are only 8 planets in the solar system, at least that we know of. The planets are pretty big and we have all these powerful telescopes. So, you’d think we’d know if there is another one around. But, some scientists aren’t so sure! According to at least two teams of researchers, there might be a few more planets beyond Pluto, lurking in the dark depths of space, just waiting to be discovered.
Here is a collection of .gifs covering first encounters/flybys of planets. The first & the new era of planetary exploration. Enjoy it.
The alien worlds run the gamut from small and lifeless chunks of rock to gargantuan globes of gas. These planets each have its own extreme features and crazy phenomena. Here are 25 amazing facts about planets.
Discovered by Sir William Herschel in March 1781, gas giant Uranus is the penultimate planet of the Solar System and currently well placed for observation in the constellation of Pisces. Despite being four times the diameter of Earth, its immense distance from the Sun (2,870 million kilometres) means that most visual observers consider discerning its tiny 3.7-arcsecond, magnitude +6, blue-green disc in backyard telescopes is achievement enough.
When the International Astronomical Union came up with an official definition of a planet in 2006, they booted Pluto out of the club and reclassified it as a dwarf planet. But some say the discovery of exoplanets requires that we revisit this definition and give Pluto a second chance.
Vesta, which has a 500km diameter and is located between Mars and Jupiter, is one of the largest known planet embryos and it came into existence at the same time as the Solar System.
The vastness of Space has thrown up another interesting planet for us to study. Recently, astronomers have discovered a cold planet situated in a binary star system located nearly 3000 light-years from our Solar System.
The planet Neptune used to be a hypothetical planet—it was predicted to exist but had never been seen. In fact, many other hypothetical planets have been proposed. Some have been ruled out, but others might have actually existed in the past and may even exist now. Here is a list of the most 5 hypothetical planets proposed by scientists
Pluto has long been regarded as something of an anomaly in our solar system. Compared to neighbouring worlds, the dwarf planet has an extremely tilted orbit which sometimes brings it closer to the sun than Neptune. Now, astronomers in Spain believe it has yet another unusual feature – the world may be harbouring two supersized planet just out of reach of our telescopes.
