Watch how this video brilliantly compares planet sizes
What if all planets were the same distance from Earth as the Moon?
- A video imagines what it would look like if the planets were all the same distance from Earth as the Moon.
- The largest planets like Jupiter and Saturn would loom large in the sky.
- Mercury is the smallest planet in the solar system.
A graphic published on Twitter brings the relative sizes of planets into perspective by imagining: What if the planets were as far from us as the Moon?
Here's how that would look from a video originally created by Yeti Dynamics:
If the Moon were replaced with some of our planets
The fascinating post brings up the question: How big are the planets? If you were wondering, here's how that rundown goes (in terms of planet diameters):
- Jupiter : 142,984 km (88,846 mi)
- Saturn: 120,536 km (74897.6 mi)
- Uranus: 50,724 km (31,518.43 mi)
- Neptune: 49,244 km (30598.8 mi)
- Earth: 12,756 km (7926 mi)
- Venus: 12,104 km (7521 mi)
- Mars: 6779 km (4212.275 mi)
- Mercury: 4,879 km (3031.67 mi)
- Pluto - not currently considered a planet: 1,476.8 mi

Jonathan Zimmerman explains why teachers should invite, not censor, tough classroom debates.
- During times of war or national crisis in the U.S., school boards and officials are much more wary about allowing teachers and kids to say what they think.
- If our teachers avoid controversial questions in the classroom, kids won't get the experience they need to know how to engage with difficult questions and with criticism.
- Jonathan Zimmerman argues that controversial issues should be taught in schools as they naturally arise. Otherwise kids will learn from TV news what politics looks like – which is more often a rant than a healthy debate.
Controversial map names CEOs of 100 companies producing 71 percent of the world's greenhouse gas emissions.
- Just 100 companies produce 71 percent of the world's greenhouse gases.
- This map lists their names and locations, and their CEOs.
- The climate crisis may be too complex for these 100 people to solve, but naming and shaming them is a good start.
It marks another milestone in SpaceX's long-standing effort to make spaceflight cheaper.
- SpaceX launched Falcon Heavy into space early Tuesday morning.
- A part of its nosecone – known as a fairing – descended back to Earth using special parachutes.
- A net-outfitted boat in the Atlantic Ocean successfully caught the reusable fairing, likely saving the company millions of dollars.
