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

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Convergence 2.0: Engineers are using the "natural genius" of biological systems to produce extraordinary machines—self-assembling batteries, cancer-detecting nanoparticles, super-efficient water filters made from proteins found in blood cells. Neuroscientist and MIT President Emerita Susan Hockfield and host Jason Gots discuss what all this could mean for our future.
- "One of my tools as president was never to talk about change. People hate change. But at MIT no one could deny you the opportunity to do an experiment."
- "If we can create these spaces for convening around our most important problems, We can make progress much faster than we can by insisting that people do the work on their own. And that's the power of the university at its best."
