26Cosmic Point of No Return
If you were able to travel from the Earth to a distance of 8.3 BILLION Light Years, you would cross the ‘Cosmic Point of No Return’, where you would never be able to make it back to Earth, even if you somehow traveled the speed of light. So it’s an important philosophical point to reflect on, that there are places in our own universe that we can’t see (or get to), and will never be able to see, or get to, or communicate with, no matter how much time passes or how fast we go.
27. About 70,000 years ago, a nomadic star came within 1 light-year of the Sun and research suggests this close pass sent dozens of comets and asteroids tumbling out of our solar system.
28. It takes 243 Earth-days for Venus to rotate about its axis, yet it takes 225 Earth-days for Venus to orbit the sun. That means that, on Venus, a day takes longer than a year.
29. There are "lone planets" that roam endlessly through space without ever going into orbit. They are actually predicted to be more common than stars. Scientists believe these lone worlds were probably ejected from developing planetary systems.
30. When Uranus was discovered it was called George for about 70 years.

31Cosmic Vacuum Cleaner
Jupiter is a "cosmic vacuum cleaner." Its gravitational influence causes comets and asteroids to collide with it. The rate of impacts on Jupiter is about 2000-8000X higher than the rate on Earth. Without Jupiter, the probability of asteroid impacts with the inner planets would be much greater.
32. The Sun is actually white. Viewed from space or a high altitude, it appears as its true color white, whereas when it is viewed from a low altitude, atmospheric rendering makes it appear to be what we believe as yellow.
33. Jupiter's outermost known moon hasn't been spotted since its discovery in 2003, and is currently considered "lost."
34. The moon has "moon-quakes" and because the moon has a smaller core than earth, this causes it to ring like a bell
35. Astronomers have discovered a bizarre rogue planet named SIMP J01365663+0933473 wandering the Milky Way. The free-range planet, which is nearly 13 times the mass of Jupiter and does not orbit a star, also displays stunningly bright auroras that are generated by a magnetic field 4 million times stronger than Earth's.
