Meet 2021 PH27, which is about 1 kilometer in size and orbits the Sun in just 113 days, the second shortest known orbital period of any object in the Solar System after Mercury. TEHRAN (Tasnim) – A team of researchers led by Scott Sheppard, a staff scientist at the Carnegie Institution of Science, discovered the fastest-orbiting asteroid in the solar system. University of Chicago’s Alex Drlica-Wagner, NOIRLab’s Clara Martinez-Vazquez, Stanford University’s Sidney Mau, and Luidhy Santana-Silva of Universidade Cruzeiro do Sul interrupted their first and second nights using the Dark Energy Camera to observe the asteroid. “Although telescope time is very precious, the international nature and love of the unknown makes astronomers very willing to override their own science and observations to follow-up new interesting discoveries like this,” said Sheppard. Thank you for signing up to Space. This book will “take you on a journey” to the Moon, Mars, Saturn and the Sun, to view some of the anomalies that, it would appear, taxpayer-funded space agencies have ignored or even lied about.

Images taken by Ian Dell’Antonio and Shenming Fu. “We are so grateful for all of our collaborators who enabled us to act quickly on this discovery.”. In 1952, more than 40 years before the first hot Jupiter was discovered, Otto Struve wrote that there is no compelling reason why planets could not be much closer to their parent star than is the case in the Solar System, and proposed that Doppler spectroscopy and the transit method could detect super-Jupiters in short orbits. The story of Pluto and its largest moon, from discovery through the New Horizons flyby--Provided by publisher. © During those close solar passes, 2021 PH27's surface gets hot enough to melt lead — about 900 degrees Fahrenheit (500 degrees Celsius), the discovery team estimates. Princeton University’s Scott Carlsten, Rachael Beaton (a Carnegie-Princeton Postdoctoral Fellow), and Jenny Greene were instrumental in the second night follow-up images from Las Campanas and on the third night Pontificia Universidad Catolica de Valparaiso’s Cristobal Sifon and Camila Aro-Bunster delayed the start of their Magellan observing program to image the object through some passing clouds.

Scientists say that there are very few asteroids of such a large size in the inner solar system that exist and there is no information about them. The solar system is made up of the Sun and the 8 planets that orbit it, including Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The space rock may have originated in the main asteroid belt between Mars and Jupiter, then gotten kicked inward by gravitational interactions with one or more planets, the researchers say. Because 2021 PH27 is so close to the Sun’s massive gravitational field, it experiences the largest General Relativistic effects of any known Solar System object. SPACE.COM SENIOR SPACE WRITER — Michael has been writing for Space.com since 2010. The newfound asteroid, called 2021 PH27, is about 1 kilometer in size and is on an unstable orbit that crosses that of Mercury and Venus.
