The newly found planet is called TIC 172900988b . It orbits its dual host stars in only 200.5 Earth-days (Jupiter takes 12 Earth-years to orbit our sun once). The discovery is significant to scientists because it demonstrated it was possible to detect TIC 172900988b with a limited amount of data.
Astronomers may have detected a planet orbiting a triple star system
The GW Orionis star system has three stars orbiting each other. Now, researchers think they may have found a planet in this dancing star trio — and if it’s true, it could teach us a few things about how planets are formed.
Binary star systems are well known to both scientists and science fiction fans. Although our own solar system has one star, systems with two or even three stars are not unusual. Between 40 and 50% are binaries and 20% are triple stars systems.
Exoplanet orbits tilted 90° by unseen object – Physics World
Exoplanets have been spotted orbiting at right angles to each other by an international team of astronomers led by Vincent Bourrier at the University of Geneva.
A star and its planets are believed to form from the same rotating disc of gas and dust. Therefore, the spin of a star should point in the same direction as the plane of the orbits of its planets.
This solar sail has been orbiting successfully for more than 2.5 years | TweakTown
The LightSail 2, a small CubeSat fitted with a solar sail spanning 32 square meters (433 square feet), is still sailing through Earth's orbit two and a half years after launch.
LightSail 2 is a crowdfunded project which amassed $7 million and is run by The Planetary Society, a U.S.-based space education and outreach non-profit organization.
Exoplanets with topsy-turvy orbits found around inconspicuous star | Astronomy.com
Surprisingly, however, the more we gaze toward other stars, the more we realize that our solar system is not the norm. For example, take the three planets orbiting HD 3167, an inconspicuous star some 150 light-years away in the constellation Pisces. According to a new study published Oct.
All three known planets in this strange system could easily fit within the orbit of Mercury. The innermost planet is HD 3167b, a super-Earth about five times as massive and 1.7 times as wide as Earth. Rapidly moving in a tight orbit, HD 3167b circles its star in less than a day.
Vandenberg Space Force Base Launches Rocket with Earth's First Planetary Defense Test - The Santa
The Vandenberg Space Force Base launched the SpaceX Falcon 9 rocket Tuesday night, carrying a defense test meant to intentionally collide with an asteroid.
Colonel Rob Long, Space Launch Delta 30 commander, was the launch decision authority. "It takes the entire team for a safe and successful launch," Long said. "I congratulate NASA on achieving the first step in this program's journey on its planetary defense test mission.
Earth Is 'On Course' to Have Its Own Rings Made of Space Junk, Say Researchers | PEOPLE.com
The growing amount of space junk orbiting Earth could eventually give the planet its own Saturn-like rings , according to Jake Abbott, a mechanical engineering professor at the University of Utah, who is developing a solution with a team whose research was published last month in the science
Say Cheese, Outer Planets!

Part of its yearly grand tour of the outer solar system, NASA's Hubble Space Telescope captured new technicolor images of the giant planets: Jupiter, Saturn, Uranus, and Neptune.
By studying these fresh cosmic yearbook photos, astronomers gain insight into each planet's unique weather patterns.
Russia launches new Prichal module to International Space Station | Space
A Russian-built Soyuz rocket carrying a modified Progress cargo spacecraft and the new Prichal docking module lifted off from Baikonur Cosmodrome in Kazakhstan on Wednesday (Nov. 24) at 8:06 a.m. EST (1306 GMT).
The Progress will deliver Prichal to the orbiting lab on Friday (Nov. 26) at 10:26 a.m. EST (1526 GMT), when Prichal will dock autonomously with Russia's new Nauka multipurpose module, if all goes according to plan.
Scientists test GPS-free navigation -- GCN
GPS navigation faces particular challenges in polar regions. Not only are there disturbances in the ionosphere that disrupt signals, but geostationary orbiting satellites have limited coverage at high latitudes and relatively few polar-orbiting positioning satellites pass over the poles.
A team of researchers has developed a proof of concept that uses cosmic-ray muons as an alternative method for sending GPS signals. The subatomic particles can not only pass through the air, but also through rock, buildings and underground – areas where GPS communications are now impossible.
