Paul Wiegert from Western University's Institute for Earth & Space Exploration is now tracing the origins of these far-traveling bodies with his former undergraduate student Tim Hallatt, the lead author on the paper, now a graduate student at McGill University.

"Our solar system is big. It contains all the planets and asteroids, everywhere we've ever been or sent a spacecraft to," explains Hallatt. "But our galaxy is truly vast. It's more than 100,000 times bigger than our solar system. The Milky Way Galaxy contains all the stars we can see on a clear night plus their solar systems. When a visitor from the wider galaxy passes through our solar system, we know we have an unprecedented opportunity to study something special."
This may worth something:
Mercury transit 2019: When and where to watch
The black dot of Mercury crosses the sun's disk in a composite image made during the last Mercury transit in 2016.
* * *
Sky-watchers across much of the Western Hemisphere are gearing up for a rare celestial show on November 11, as the planet Mercury sails across the face of the sun. Known as a transit of Mercury, this is the last time humans will see this daytime sky show until 2032.
During a transit, Mercury passes between Earth and the sun, becoming a small, round silhouette against the yellow glow of the solar disk. Safe viewing is paramount at all times— never look directly at the sun without proper protection or you risk damaging your eyes.

Space news: UK firm to 'leave Solar System and inhabit Milky Way planet' with new rocket | UK |
Also known as nuclear fusion, the technology breakthrough is a form of renewable electric power generation created during the same fusion process of a star, just in a controlled environment and it could “save the world”. Currently, the Joint European Torus (JET) is the world’s largest operational facility located at the Fulham Centre for Fusion Energy in Oxfordshire, where scientists work around the clock to scrutinise the technology.
However, privately owned British company Pulsar Fusion want to change the game, as CEO Richard Dinan hopes his generation will be the one to inhabit another planet.

That Interstellar Comet Is Carrying Water From Beyond Our Solar System
Available evidence points to there being a lot of water out there in the Universe, beyond the Solar System. Detecting it and studying it, however, is not exactly easy - unless the water comes to us. Now, some of it has, carried in on a comet from light-years away.
According to a new analysis of 2I/Borisov, submitted to The Astrophysical Journal Letters and uploaded to pre-print resource arXiv , the interstellar comet is outgassing water vapour.
Best pictures of the solar system from the decade you were born - Business Insider
For decades, scientists have pointed Earthly lenses toward the sky to capture images of the cosmos. Even the earliest rockets that launched off the planet brought cameras into space.
At first, our photos of the solar system came back grainy, unclear, and colorless. The very first image taken in space, for example, came from a 33mm motion-picture camera that American scientists strapped to a captured German rocket and launched off Earth at the end of World War II. The camera fell back to Earth and shattered, but the film survived.
OffWorld's Smart Robots Could Swarm Solar System to Help Astronauts and Settlers | Space
WASHINGTON — Future lunar explorers could have smart robots ready to help them thanks to OffWorld, a company that plans a fleet of industrial machines for destinations all over the solar system.
The California-based company already has some undisclosed Fortune 500 companies paying it to deploy robots on Earth for applications such as mining. And while the tech is all early stage, OffWorld said it plans to go a lot further.
Alien comets may be common, object from beyond Solar System suggests | Science | AAAS
The comet is an alien intruder from another star system. But 2I/Borisov, the second known interstellar visitor after far smaller 'Oumuamua , discovered in 2017, looks remarkably like a normal comet from our own Solar System: an object a few kilometers across spewing carbon monoxide gas, water vapor, and dust.
"Our current telescopes are not powerful enough to detect all of these objects," says Bryce Bolin, an astronomer at the California Institute of Technology in Pasadena and lead author of the new study. But in the future, he says, large telescopes will be able to catch these visitors more often, perhaps two or three times a year.
