Ar Fehefin 27, amser lleol, cyhoeddodd Asiantaeth Ofod Ewrop yr arsylwi a dadansoddi diweddaraf o'r asteroid bron i'r Ddaear 2024 yr4, gan gadarnhau bod tebygolrwydd y corff nefol yn taro'r lleuad ym mis Rhagfyr 2032 tua 4%, ond nid yw'n peri bygythiad uniongyrchol i'r ddaear .
2024 YR4 is an asteroid with a diameter of about 80 meters discovered at the end of 2024. Early monitoring had caused concerns about impact with the Earth due to data uncertainty. In February this year, the European Space Agency has clearly ruled out its risk of hitting the Earth, and current observation data show that the probability of hitting the Earth is almost sero .
According to the European Space Agency's Planetary Defense Office, if 2024 YR4 hits the moon, it may form a crater with a diameter of about 1 km on the lunar surface and stir up debris into the Earth-Moon space, which may pose certain risks to spacecraft and satellites in orbit.
Dywedodd yr Asiantaeth Ofod Ewropeaidd nad oes angen unrhyw fesurau ymyrraeth ar hyn o bryd a bydd yn parhau i weithio gydag asiantaethau rhyngwladol i olrhain newidiadau orbitol y corff nefol . Disgwylir y cyfle arsylwi allweddol nesaf yn 2028.
