Astronomers in Hawaii have detected the Yarkovsky effect – a minuscule push imparted by sunlight – for asteroid Apophis. The effect is particularly important for Apophis, because it relates to the possibility of an Earth impact in 2068.

NASA OSIRIS-REX Mission Springs Leak After Touching Asteroid - The New York Times
NASA's effort to grab a piece of an asteroid on Tuesday may have worked a little too well. The spacecraft, OSIRIS-REX, grabbed so much rock and dirt that some of the material is now leaking back into space.
A few rocks wedged in the robotic probe's collection mechanism prevented a flap from fully closing. In images taken by the spacecraft, scientists could see bits of asteroid coming out. Dr. Lauretta estimated that each image showed about 5 to 10 grams — up to about a third of an ounce — of material floating around the collector. That is a significant loss as the mission's aim is to bring back at least 60 grams of asteroid dirt and rocks.

2 small asteroids zip by Earth closer than the moon today | Space
Two small asteroids will fly by Earth today (Oct. 19) at a range that's closer than the moon, a space rock double flyby that comes as NASA gears up for an asteroid encounter of its own.
The asteroids 2020 UX and 2020 TF6, both discovered in the last week, will be less than half the distance of Earth's moon (when they pass by today, but pose little threat to our planet. The moon, on average, is about 239,000 miles (385,000 kilometers) from Earth.
Neil deGrasse Tyson: US election day asteroid could hit Earth | South Wales Argus
AS IF 2020 hasn't been traumatic enough, an asteroid could hit Earth on the eve of the US Presidential Election on Tuesday.
The asteroid, named 2018VP1, measures just under two metres and poses no threat to Earth, but is a reminder that given the thousands of bodies that orbit near to the the planet, some could and do strike us.
Astrophysicist, Neil deGrasse Tyson, commented that the fridge-sized asteroid, discovered by the Palomar Observatory in California, may 'buzz-cut' the Earth on Tuesday, November 2.
