However, Harvard's Professor Avi Loeb believes the bizarre object that entered the solar system in 2017 was no regular space rock.

Harvard University’s distinguished Department of Astronomy chair has revealed in his new book how aliens may have recently deposited some space trash in our cosmic neighbourhood.
On September 6, 2017, an object originating from the star Vega 25 light-years distant, collided with Earth’s atmosphere, before bouncing towards the Sun on September 9.

Difference between asteroids, meteors and comets - NASA explains how to tell them apart | Science
The dawn of our solar system saw a gargantuan cloud of swirling dust and cosmic debris circling the nascent Sun. This space dust proceeded to collide with each other to create larger bits of rock. Over unimaginable lengths of time, this process of accretion continued until they grew to form the recognisable planets of our solar system.

The space agency wrote in a blog post: “Amazingly, many of these mysterious worlds have been altered very little in the 4.6 billion years since they first formed.
Hayabusa2 mission confirms return of an asteroid sample, including gas, to Earth - CNN
(CNN) The Hayabusa2 mission successfully collected a sample from a near-Earth asteroid and returned it to Earth -- as well as the first gas sample from deep space, according to the Japan Aerospace Exploration Agency , or JAXA.
We're Never Going to Mine the Asteroid Belt
From Ellen Ripley in Alien and Dave Lister in Red Dwarf, to Sam Bell in Moon and The Expanse's Naomi Nagata, the grittier end of interstellar drama would be bereft if it weren't for overalled engineers and their mineral-processing operations.
It's such an alluring vision that real money has been put toward its realization. Alphabet Inc.'s Larry Page and Eric Schmidt, and Hollywood filmmaker James Cameron (director of the Alien sequel Aliens) all invested in Planetary Resources Inc., which raised venture finance with its mission of mining high-value minerals from asteroids and refining them into metal foams that could be shot back down to Earth. Deep Space Industries Inc.

Japan Pleased with Latest Asteroid Samples
Japanese officials say they are pleased with the quality of asteroid material collected by a spacecraft and returned to Earth.
Last week, officials from the Japan Aerospace Exploration Agency, JAXA, described the samples, which were collected from the Ryugu asteroid in July 2019. Ryugu sits more than 300 million kilometers from Earth.
Japan's unpiloted Hayabusa2 spacecraft removed the material after blasting a hole into the asteroid.
Sydney's rivalries survive like cockroaches after an asteroid but facemasks bring us together
As masks become mandatory in Greater Sydney – a decision long overdue to many minds – we will all wear one for the team on trains and buses, sitting in cinemas and so forth, and look just a little bit more alike.

Yet scratch the surface of "we're all in this together" and you'll still find it, from Sydney's inner west to the south-west to the upper northern beaches: a grain of false pride, or call it NIMBYistic rivalry, lingering like the proverbial cockroach that survived the asteroid collision.
2021 Is Going to Be a Big Year in Space — Here's What to Watch for This Year | Travel + Leisure
While 2020 was, by and large, a challenging year, it was a rather triumphant one for the international space industry. Between the return of human spaceflight to American soil (thanks, SpaceX !), three Mars mission launches (for the United States, China, and the United Arab Emirates), and the successful recovery of samples from the moon and the asteroid Ryugu (by China and Japan, respectively), it was certainly an impressive 12 months.
In 2020, SpaceX’s Crew Dragon vehicle became the first privately built spacecraft to be certified by NASA to bring astronauts into space, sending six astronauts to the International Space Station between one test flight and one operational mission. But in 2021, SpaceX will have competition.
Meteor showers in 2021 that will light up night skies | Deccan Herald
All year long as Earth revolves around the sun, it passes through streams of cosmic debris. The resulting meteor showers can light up night skies from dusk to dawn, and if you're lucky you might be able to catch one.
If you spot a meteor shower, what you're really seeing is the leftovers of icy comets crashing into Earth's atmosphere. Comets are sort of like dirty snowballs: As they travel through the solar system, they leave behind a dusty trail of rocks and ice that lingers in space long after they leave.
