..., then you would weigh 20 times more than you do on Earth. If the Sun was a bloated red giant, as it will be one day in the far future, the much weaker pull at the surface of this puffed-out star means you would be 50 times...
...Neptune and Pluto have a 3:2 resonance, meaning that Neptune will orbit the Sun three times in the same time that it takes Pluto to orbit the Sun twice. The discovery, while not unique, is relatively uncommon in exoplanet detections as relatively few...
... Earth years. If a planet of that size is orbiting the sun beyond Neptune, it will affect the orbits of nearby objects. The planet appears to have an elliptical orbit and the closest it comes to the sun is about two hundred and fifty astronomical...
..., and it whizzes round its host star once every 14.4 days. All of the planets in the Kepler-90 system are closer to their central star than the Earth is to the Sun. Because Kepler-90i orbits so close to its host star, its average...
... this 300 kilometre wide object was discovered about 80 AU from the Sun; an astronomical unit is the mean distance from the centre of the earth to the centre of the sun - so around 149.6 million kilometres. Neptune for comparison is 30 AU away, which...
... to find their previous positions, Namouni and Morais found these objects were orbiting the Sun on a plane perpendicular to the planetary motion going on at the time of the Solar System’s formation. Not only that but they were located far from...
