The solar system has too many moons – it's time for a cull | New Scientist

OK, WHAT I’m about to say may cause some distress. You remember how it was with Pluto? In 2006 , the International Astronomical Union (IAU) voted to downgrade the much-loved ninth planet to a mere dwarf planet . More than a decade later , it seems some people still haven’t gotten over it. But I’m still going to say it: things are getting a little out of hand with the solar system’s moons.

On 7 October, astronomers announced the discovery of 20 moons around Saturn . This took the total number of moons in the solar system to 214. The …

Quite a lot has been going on:

To-scale solar system now orbiting around CBEC

A new cosmic art installation on The Ohio State University campus represents our solar system and bridges the arts and sciences in an astronomical way.

“The Solar System to Scale” comprises 10 mixed-media kiosks that begin with a “sun” kiosk on Woodruff Avenue outside the Chemical and Biomolecular Engineering and Chemistry Building and end with a “Pluto” kiosk near the Chadwick Arboretum Learning Gardens on West Campus! How Many Moons are in the Solar System? - Universe Today www.universetoday.com /15516/how- many - ...in- ...system In this region of the Solar System , every planet has a substantial system of Moons ; in the case of Jupiter and Saturn, reaching perhaps even into the hundreds. So far , a total of 170 moons have...!! The spacing between the kiosks is a to-scale representation of each planet’s distance from the sun.

The installation was funded by a gift from alumni M. Andrew and Sandra L. Ross . The Rosses had their first discussion with the university about their vision to bring “The Solar System to Scale” to campus in July 2015. The idea came from Andy’s fascination with space as a child, he said, recalling how he looked up to the sky one night and asked his dad how close the nearest star was. Since that point, he’s never stopped trying to grasp the size of the universe.

A faux Saturn moon Titan on Earth could solve solar system mystery | Fox News

Saturn's moon Titan has a unique surface that's hard to see through its nitrogen-rich atmosphere. (NASA/JPL/University of Arizona)

Big, schmancy compounds keep popping up  all over the solar system , and new research may help clear up confusion about how they form in so many places.

"These dunes are pretty large," study senior author Ralf Kaiser, a chemist at the University of Hawaii at Manoa, told Space.com, nearly as tall as the Great Pyramid in Egypt, he added. "If you want to understand the carbon and hydrocarbon cycle and the processes of hydrocarbons on Titan, it's really important to understand, of course, where the dominant source of carbon comes from."

On Titan, there's a straightforward mechanism that scientists know likely builds polycyclic aromatic hydrocarbons: These large molecules can form in the moon's thick atmosphere and settle down to the surface! What are the moons of the solar system and how many are there ...430432 Throughout the solar system , there are 187 known moons or 196 if you count those belonging to the dwarf planets. Considering all of this, you might feel cheated. All of those moons , and we only ...!! But the same family of compounds has been found on plenty of worlds that boast no such atmosphere, like the dwarf planets  Pluto  and  Ceres  and the Kuiper Belt object  Makemake .

Many things are taking place:

This is the closest solar system to Earth containing multiple planets - CNN

(CNN) Just 11 light years from earth is the GJ 15 A star system with two planets orbiting a red-dwarf star. This makes it the closest solar system to Earth that contains multiple planets.
