The planets aligned
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, (Pluto).
And now for some interesting planetary tidbits:
All the planets are basically in the same plane, due to the angular momentum of the solar system.
Venus is considerably hotter than Mercury, despite being further from the sun, due to greenhouse gases in the atmosphere.
Seasons on Uranus last for 21 earth-years, since Uranus takes 84 earth-years to orbit the sun.
Jupiter's tremendous gravitational field plays a huge protective role by drawing interstellar objects away from Earth.
The sun contains more than 99% of all the mass in the solar system. (Earth could fit inside the sun 1,300,000 times.)
This quite nicely demonstrates the vast emptiness of space, even within our own solar system. http://joshworth.com/dev/pixelspace/pixelspace_solarsystem.html
The furthest man has ever gone from earth is the moon, about 240k miles, or 0.00000004 light years.
The furthest man-made object from earth is the Voyager 1 spacecraft (launched in 1977, traveling at about 40,000 mph), about 12 million billion miles from earth, or 0.002 light years.
The closest star to the sun is Proxima Centauri, at a distance of 4 light years. #Planets #Space
