The Croatian Astronomical Union has reported that a meteorite fell in the Rijeka area on the night of August 14.

Experts from the Croatian Astronomical Union estimate that a lump weighing about 150 grams ended up on the ground, but say they will not go looking for it because of the dangerous and impassable terrain.

The fireball was filmed by cameras of the Croatian Meteor Network from Buzet, Hum, Pula, Roč and Tićan, but also by cameras of the Global Meteor Network from Italy and Slovenia, and even from Prague.

Newly discovered asteroid 2021 PH27 orbits the Sun in just 113 days

There are new discoveries to be made, even in the inner solar system. This was highlighted this past week with the announcement of the discovery of tiny asteroid 2021 PH27. The asteroid orbits the Sun in just 113 days, the shortest orbital period for any known asteroid and the second shortest orbital period for any object in the solar system next to the planet Mercury, at 88 days.

The discovery was made by astronomer Scott S. Sheppard (Carnegie Institution for Science) after searching through images taken by Ian Dell'Antonio and Shenming Fu (both Brown University) at evening twilight on August 13, 2021. Subsequent observations with multiple telescopes around the world enabled astronomers to confirm the asteroid's orbit.

The initial discovery observations were made using the Dark Energy Camera (DECam) based at the National Science Foundation's Blanco 4-meter telescope at the Cerro Tololo Inter-American Observatory (CTIO) complex in Chile. Although the primary mission for the Dark Energy Camera is the study of cosmic expansion, the Brown University astronomers agreed to use DECam at the beginning of their observing run to take wide-field images in the fading twilight.

Spectacular meteor fireball over South Africa

fireball
If a small asteroid or large meteoroid survives its fiery passage through the Earth's atmosphere and lands on its surface, it is then called a meteorite, scientists say.

But what many South Africans thought was a spectacular meteor shower early on Tuesday evening was actually a "bolide", a very bright meteor that often explodes on entry into the Earth's atmosphere and can be seen over a wide expanse. It comprises 1 to 10-metre rocks of around 1 648°C and can also be called a fireball.

Dr Daniel Cunnama, science engagement astronomer at the SA Astronomical Observatory, said: ''A bolide is a single meteor breaking up on entry. A bolide is a very bright meteor.
