For more than five years , astronomers have been on the hunt for a mysterious planet they believe may be orbiting the Sun at a much further distance than Uranus and Neptune.
* * *
The evidence suggested a Neptune-sized planet orbits our Sun in a highly elongated orbit beyond Pluto. This hypothetical planet may have a mass about 10 times that of Earth and orbit about 20 times farther from the Sun than Neptune, the eighth and farthest known planet from the Sun. But the hypothetical planet is still pure math.

The Fundamental Connections Between the Solar System and Exoplanetary Science - Astrobiology
Over the past several decades, thousands of planets have been discovered outside of our Solar System. These planets exhibit enormous diversity, and their large numbers provide a statistical opportunity to place our Solar System within the broader context of planetary structure, atmospheres, architectures, formation, and evolution.
Meanwhile, the field of exoplanetary science is rapidly forging onward towards a goal of atmospheric characterization, inferring surface conditions and interiors, and assessing the potential for habitability. However, the interpretation of exoplanet data requires the development and validation of exoplanet models that depend on in-situ data that, in the foreseeable future, are only obtainable from our Solar System.

The ordinary chondrite (OC) meteorites originate from at least three different original parent asteroids with slightly different chemical compositions, and are designated H, L, and LL for their high, low, and very low iron contents.

A Field Guide to the Magnetic Solar System - Eos
Congratulations! With the IP9, the new interplanetary model in Eos's signature line of magnetic compasses, you've chosen a travel companion that will serve you as best it can on the many GPS-challenged bodies of our solar system—be your plans a hike on Mercury, a ride on Mars, or a glide over Neptune.
Before you start using your compass, please note that your warranty is voided when you drop your IP9 onto a hard surface or into a high-pressure or high-temperature environment, or store it unshielded from magnetic fields during extended periods of interplanetary travel.
MOZAMBIQUE: Solar Century to install a PPP solar system (11.2 MW) for Syrah | Afrik 21
Syrah Resources, an Australian graphite mining company, recently signed a public-private partnership (PPP) agreement with Solar Century to implement an 11.2 MW solar hybrid project at its graphite mining site in Balama, Mozambique. The specific PPP model agreed between the two parties is the Boot model (build, own, operate, transfer).
The London-based solar energy provider, Solar Century, will equip the future hybrid solar power plant with an 8.5 MWh battery storage system. The system will supply electricity to the Balama graphite mine, thus securing the power supply to its facilities. The electricity generated by the hybrid solar system will also reduce the site’s consumption costs.
Christmas Day Asteroids: Space Rocks Flying Past Earth on 12/25
2014 SD224, which has an estimated diameter of 689 feet and is scheduled to make its close approach at 3:20 p.m. EST, will be in good company on Christmas.
With over nearly 7,000 positive reviews on Amazon and a 4.4/5 rating, it's not hard to see why the Gskyer telescope is a fan-favorite. This option features a 70mm aperture and fully coated optimal lenses to offer a crisp, clear view of the night's sky. Tech savvy stargazers will appreciate the smart phone adapter and wireless camera remote, making it possible to view constellations from your screen.
“Christmas Star” visible this week | Newberry Observer
In 1610, Italian astronomer Galileo Galilei pointed his telescope to the night sky, discovering the four moons of Jupiter – Io, Europa, Ganymede, and Callisto.

NEWBERRY COUNTY — Skywatchers were in for an end-of-year treat. What has become known popularly as the “Christmas Star” is an especially vibrant planetary conjunction easily visible in the evening sky over the next two weeks as the bright planets Jupiter and Saturn come together. The sight culminated on the night of Dec. 21.
