(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.

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!

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.
Today's Your Last Chance to Help Name an Alien Solar System-- | Space
Right now, it's a solar system known only by the designation HD 17156. Before 2019 ends, it will bear an entirely different second moniker — perhaps one suggested by you.
That's because the International Astronomical Union (IAU), which oversees all celestial nomenclature, has decided to mark its 100th anniversary by letting each country name a planetary system!

This makes it the...!! The United States got HD 17156, and today (Oct. 15) is the last day for the public to submit proposed names, so get thinking.
The IAU has put some constraints on the project, of course. First, it needs two names: one for the planet , one for the star. They should be connected in some way that is open-ended enough to allow for naming other, not-yet-discovered stars or planets in the same system along the same principals.

"The proposed names should be of things, people, or places of long-standing cultural, historical, or geographical significance, worthy of being assigned to a celestial object," the IAU wrote in its guidelines . The names don't have to be related to astronomy, although they can be.
This may worth something:
Oddball solar system throws planet formation theories into question | Science | AAAS
A solar system 31 light-years away is challenging astronomers' theories about how some types of planets form.
One leading notion about how the gas giants in our solar system—Jupiter, Saturn Uranus, and Neptune—developed is that agglomerations of dust and small pebbles eventually grew large enough to gravitationally attract large amounts of even light gases such as hydrogen and helium!

But that sort of planetary evolution doesn't seem to work for all solar systems.
Take the star dubbed GJ 3512 and its retinue of planets: The parent star is a red dwarf about one-eighth the mass of our own sun orbited by two gas giants (depicted in an image from a video simulation above). The larger planet, whose presence has been confirmed, is almost half the mass of Jupiter and orbits the star once every 214 days , researchers report today in Science . Its suspected companion, which orbits farther out and apparently circles the star every 3.8 years or so, may weigh at least half as much as Saturn.
Earth-Like Planets May Be Common Outside Our Solar System, Scientists Discover - VICE
Scientists have directly observed the rocky guts of exoplanets, which are worlds from different star systems, by watching the fallout of these objects crashing into the corpses of dead stars.
This mind-boggling technique has revealed that exoplanets are similar in composition to planets in our own solar system, implying that worlds like Earth may be plentiful in our galaxy, according to a study published on Thursday in Science .
"It's pretty cool because this is really the only way to measure the geochemistry of exoplanetary bodies directly," said lead author Alexandra Doyle, a graduate student of geochemistry and astrochemistry at UCLA, in a phone call.
Co-author Edward Young, a professor of geochemistry and cosmochemistry at UCLA, added that the study represents "the first time such an advanced way of looking at the geochemistry of these bodies has been used," in the same call.
