Pictures of a potentially hazardous asteroid which looks like a “sweet dumpling” have been beamed to Earth by a Japanese spacecraft.
Hayabusa 2, which was launched in 2014, is now about 215 km (133 miles) away from the newly-photographed asteroid Ryugu.
The spacecraft is expected to arrive at the asteroid on June 27.
Jaxa, the Japanese Aerospace Exploration Agency, will monitor the object for a year-and-a-half and collect rocky samples to bring back to Earth.
We have seen Ryugu rotating! A series of 52 images taken at a distance of about 700km show an angular-looking asteroid. https://t.co/nGff3YIPLs pic.twitter.com/Yo0JgfNz6s

The new images of the asteroid were captured by Hayabusa 2’s onboard camera when it was between 700km and 650km away (434-403 miles). They have been shared as a gif.
In the animation, the asteroid surface appears to be very angular, and pitted with dents or craters, Jaxa said, with one large crater exceeding 200 metres in diameter.
Makoto Yoshikawa, Hayabusa 2 mission manager at Jaxa, likened the images to those taken by Nasa’s OSIRIS-REx of the asteroid Bennu.
At a distance of only 330 – 240km from Ryugu, we are starting to make out the shape! Ryugu seems to have an equatorial ridge and deep craters; a structure not unlike the destination of @OSIRISREx, asteroid Bennu. Where will we land? https://t.co/Ad0NUC5dfZ pic.twitter.com/sYax26xeuZ

He said: “So far, the asteroids we have explored have been different in shape, so Ryugu and Bennu could be the first time two similar-shaped asteroids have been examined.
“It will be interesting to clarify exactly what this similarity means scientifically.”
Hayabusa2 has imaged Ryugu from 920km and we’re starting to see the shape. It looks like… a dango-type asteroid! (Actually, that’s a Japanese sweet dumpling. But the shape seems to be similar so far…)https://t.co/2KRADT3Ybc pic.twitter.com/qlkBto9jtV

Ryugu’s orbit is retrograde, which means it is moving in the opposite direction to the Sun and the Earth.
Its diameter is about 900 metres and looks like a “sweet dumpling”, according to Jaxa, with the equatorial part wider than the poles.
Ryugu, which is short for 162173 Ryugu, has been classified as a potentially hazardous asteroid, meaning it has the capability to make exceptionally close approaches to the Earth and is large enough to cause significant damage in the event of impact.
