How rare is our Solar System? In the 30 years or so since planets were first discovered orbiting stars other than our Sun, we have found that planetary systems are common in the Galaxy. However, many of them are quite different from the Solar System we know.
Our international team of astronomers has tackled this issue in research published in Nature Astronomy . We found that between 20% and 35% of Sun-like stars eat their own planets, with the most likely figure being 27%.
Spot the elusive planet Mercury at its 'greatest elongation' from the sun this evening | Space
Of the five "naked-eye" planets in Earth's night sky, Mercury tends to be the most difficult to spot because the tiny planet tends to linger in the sun's bright glare.
But tonight (Sept. 13) Mercury will reach its farthest separation from the sun as seen from Earth, also known as its greatest eastern elongation, which makes this the best night to look for the planet during its current evening apparition.
Why are planets round? | KRQE News 13
(AP THE CONVERSATION) The ancient Greeks proved over 2,000 years ago that the Earth was round and figured out how big it was by using simple observations of the Sun.
But how do people know this today? When you drop anything, gravity causes it to fall directly toward the center of the Earth, at least until it hits the ground. Gravity is a force that is caused by nearly everything that has mass.
Earthlike Planets In Other Solar Systems? Look For Moons – Eurasia Review
Finding an exact copy of the Earth somewhere in the universe sounds like a far-fetched notion, but scientists believe that because Earth happened in our solar system, something similar is bound to exist someplace else.
"In our solar system, we have an average of 20 moons orbiting around each planet. So, we suspected there are moons around planets in other systems, too. There is really no reason why there shouldn’t be any," said Eggl, a professor in the Department of Aerospace Engineering at UIUC.
A New Way to Search for Exomoons - Universe Today
We’d love to find another planet like Earth. Not exactly like Earth; that’s kind of ridiculous and probably a little more science fiction than science. But what if we could find one similar enough to Earth to make us wonder?
How could we find it? We progress from one planet-finding mission to the next, compiling a list of planets that may be “Earth-like” or “potentially habitable.
Planets Could Be a Huge Boon for Starfield's Modding Scene
Bethesda’s open-world RPGs are a modder’s paradise.
There’s a unique element of Starfield that could be particularly fruitful for the game’s modding community, though it's a feature that faces Starfield ’s base game with some interesting challenges.

This week is all about the Moon and the planets. With Monday being First Quarter Moon, our satellite is becoming too bright for high-level stargazing, so spend the post sunset hours looking to the southeastern sky.
Planet maven Shannon Curry takes over MAVEN mission to Mars | Berkeley News
Planetary physicist Shannon Curry is the new principal investigator for the MAVEN mission to Mars, which has been studying the atmosphere and magnetic field of the planet since 2014.
As a young girl growing up in Cincinnati, Shannon Curry repeatedly asked her parents about the night sky, especially the planets, but as non-scientists, they seldom had answers. “That is what college is for,” her parents told her.
