Asteroid warning: NASA tracks a 21,300mph asteroid on possible collision course in 2020 | Science

The asteroid is trapped in the inner solar system and crosses Earth’s orbit similarly to Asteroid 1862 Apollo.

NASA said: “Some asteroids and comets follow orbital paths that take them much closer to the Sun and therefore Earth – than usual.

“If a comet or asteroids approach brings it to within 1.3 astronomical units of the Sun, we call it a Near-Earth Object.”

And here's another article:

Impact crater data analysis of Ryugu asteroid illuminates complicated geological history

It is hoped that the collected data can be used as a basis for future asteroid research and analysis.

These results were first published in the American Scientific Journal ' Icarus ' on November 5 2019.

The Japan Space Agency (JAXA)'s Hayabusa 2 has been used to carry out various missions to increase our understanding of the spinning top-shaped, Near-Earth asteroid Ryugu. Since arriving in June 2018, the unmanned spacecraft has taken samples and a great number of images of the asteroid. It is hoped that these can reveal more about Ryugu's formation and history.

Quite a lot has been going on:

Hayabusa 2 Leaves Asteroid Ryugu and Heads Home - Sky & Telescope

The Hayabusa 2 spacecraft has completed its mission at asteroid Ryugu — including collecting samples — and is now journeying back to Earth.

Most interplanetary missions end with the spacecraft simply falling silent on an alien world; a very few make the journey home. On Wednesday, November 13th, Japan's Hayabusa 2 spacecraft started such an adventure as it fired up its engines, leaving asteroid 162173 Ryugu for a long journey home with its precious cargo: samples of the asteroid.

Advocates promote planetary defense mission ahead of ESA ministerial - SpaceNews.com

WASHINGTON — A group of planetary defense advocates is asking European governments to fund a mission to a near Earth asteroid, three years after a similar mission failed to win approval.

At a press conference in Berlin Nov. 15, backers of the proposed Hera mission said more than 1,200 scientists and other supporters had signed a letter calling on European Space Agency member states to fund the mission at their ministerial meeting later this month in Spain.

CU Boulder scientist honored with asteroid named for him

The International Astronomical Union recently announced that it would honor Sánchez by renaming asteroid 2000 VH57 in his honor.

Now named Paulsánchez, the binary system is a pair of asteroids orbiting each other in the asteroid belt.

Sánchez, a senior research associate at the Colorado Center for Astrodynamics Research within the Ann and H.J. Smead Department of Aerospace Engineering Sciences at CU Boulder, did not have a background in astrodynamics before coming to the university 10 years ago. But he combined his expertise in granular dynamics and quantum chemistry to dive into asteroid science.

Fossil ice found in meteor is the first direct evidence of ice in asteroids | Natural History

High-resolution scans of a 4.6 billion- year-old meteorite have revealed 'fossilised ice', showing for the first time direct evidence that when early asteroids formed they incorporated frozen water into their matrix.

Researchers from London's Natural History Museum and several Japanese institutes including Tohoku University have discovered the fossil ice in a meteorite weighing just 82 grams that slammed into Algeria in 1990. Officially called Acfer 094, this meteorite was a piece of a larger asteroid that formed during the early days of the Solar System.
