Product Information

The Search for Planet X is an app-assisted deduction game. Players will be using logic to figure out where different celestial bodies are, publishing papers on their findings. Hopefully, being the first person to discover the elusive ‘Planet X’. Setting Up The Solar System Some may therefore feel that after finding Planet X once or twice, they don’t need to keep looking. For players with a penchant for puzzle-solving, though, it’ll be a delight to immediately misplace it and begin searching again. The app will ask which side of the board you’re facing and give you some starting information (with more experienced players being given less). The Laws Of Logic Brown, Mike (August 2008).

The discovery was made based on mathematical calculations of its predicted position due to observed perturbations in the orbit of the planet Uranus. The discovery was made using a telescope since Neptune is too faint to be visible to the naked eye, owing to its great distance from the Sun.

In December 2015, astronomers at the Atacama Large Millimeter Array (ALMA) detected a brief series of 350GHz pulses that they concluded must either be a series of independent sources, or a single, fast moving source. Deciding that the latter was the most likely, they calculated based on its speed that, were it bound to the Sun, the object, which they named "Gna" after a fast-moving messenger goddess in Norse mythology, [97] would be about 12–25 AU distant and have a dwarf planet-sized diameter of 220 to 880km. However, if it were a rogue planet not gravitationally bound to the Sun, and as far away as 4000 AU, it could be much larger. [98] The paper was never formally accepted, and has been withdrawn until the detection is confirmed. [98] Scientists' reactions to the notice were largely sceptical; Mike Brown commented that, "If it is true that ALMA accidentally discovered a massive outer Solar System object in its tiny, tiny, tiny, field of view, that would suggest that there are something like 200,000 Earth-sized planets in the outer Solar System ... Even better, I just realized that this many Earth-sized planets existing would destabilize the entire Solar System and we would all die."

Retrieved 18 July 2016.If you’ve ever done any of those logic grid puzzles, you’ve got a good idea of what you’ll need to do in The Search for Planet X. It’s a process of elimination and using the scant information you’re given to lead to logical conclusions. It’s a really satisfying thing when it goes well, and the Eureka moments are fantastic. When you put two and two together and come up with four, well, that makes you feel like some kind of genius, and it’s great. Lowell dubbed the putative body Planet X; his persistence led to the 1930 discovery of Pluto. By 1978, scientists had concluded that Pluto was too small to affect the larger bodies, and began searching for a large missing planet. First, decide whether you want to play in Standard Mode (12 sectors) or Expert Mode (18 sectors). Place the sun disc in the centre of the board and overlay the earth board so that the yellow arrow is pointing into sector 1. The 4 sides of the board are marked with a symbol relating to one of the four seasons. Each player should now take a note sheet relating to the side closest to them. These sheets show the night sky from their relative perspective, making it easier for the players to orient themselves. Iorio, Lorenzo (2017).

Locate Planet X (5 time) – Once you’re ready to locate Planet X, the app will ask you both which sector you think it’s in (this can be any sector, not just somewhere in the visible sky) and also what is located in both of the adjacent sectors. de la Fuente Marcos, C.; de la Fuente Marcos, R.

In 2005, astronomer Mike Brown and his team announced the discovery of 2003 UB 313 (later named Eris after the Greek goddess of discord and strife), a trans-Neptunian object then thought to be just barely larger than Pluto. [58] Soon afterwards, a NASA Jet Propulsion Laboratory press release described the object as the "tenth planet". [59]
