I found this pretty darn interesting and wanted to share.
1. Our home: the solar system
This is the solar system, our familiar cluster of one star, eight planets, an asteroid belt, and a whole lot of moons, comets, and tiny bits of debris. This beautiful map from National Geographic shows our entire history of exploring this cluster — our crewed landings on the moon, our probes on Venus, Mars, asteroids, and comets, our orbiters around the Sun, Saturn, Mercury, Jupiter, and Saturn, and our flybys of Uranus and Neptune. But with maps like this, there's always one important caveat to keep in mind...
2. The solar system is mostly empty space
...maps of the solar system are almost never to scale. In reality, the solar system is a vast, empty area, populated by a single star and a few tiny, spaced-out planets with huge, huge gaps between them. If you somehow flew by it at the speed of light, you might well miss it entirely, and simply see a bright sun surrounded by nothingness. Josh Worth's If the Moon Were Only 1 Pixel is the best way to see how empty the solar system really is.
3. The moon is surprisingly far away from Earth
Compared with the overall vastness of space, the moon is very close to us: it's just 238,900 or so miles away. But compared with our daily experience, absolutely everything in space is really, really far apart. In the gap between us and the moon, you could neatly slide in all seven of the other planets, with a bit of room to spare. That includes Saturn and Jupiter, which are about 9 and 11 times as wide as Earth, respectively.
4. The sun is absolutely ginormous
It might not be a big surprise to you that the sun is really, really big. But this image, part of a great series on the size of astronomical objects by John Brady, underscores that it's vast on a scale that's simply difficult for our puny human minds to understand. We think of the Earth as a big place: flying around the equator on a 747 at top speed would take about 42 hours. Flying around the sun at the same speed, by contrast, would take about six months.
5. The United States, at night
We've launched thousands of satellites to learn about a place most people don’t consider "space": Earth. Images of Earth from space have provided data on carbon dioxide emissions, previously undiscovered seafloor mountains, and deforestation in the Amazon. This composite image, made up of photos taken by NASA and NOAA satellites, shows the remarkable impact of artificial lights across the US at night. Looking solely at these blobs and streaks of light pollution, you can figure out the location of cities, suburbs, and even interstate highways.
6. 556 asteroids have hit Earth's atmosphere
Every so often, a small piece of space comes down from the sky and hits us. This map shows 556 small asteroids that have burned up in Earth’s atmosphere over the course of about two decades. Most of them disintegrated harmlessly, but one exploded over Chelyabinsk, Russia, in 2013, breaking thousands of windows and causing injuries. The odds of a more destructive asteroid hitting us are low, but it does happen from time to time — and many experts say we’re not doing enough to track and prevent such incidents.
7. 300,000 pieces of space junk
After decades of using space for communication and defense, we’ve left it pretty polluted: there are now an estimated 300,000 pieces of space junk a centimeter or bigger in Earth’s orbit. Some are deactivated, decades-old satellites, but most are shards of metal — the result of rockets that exploded after use, or satellites that collided. Experts are worried that growing levels of space junk could make some orbits difficult or impossible to use, and space agencies are requiring satellite operators to be more careful with their equipment after it's decommissioned.
