A Deep and Wide Twilight Survey for Asteroids Interior to Earth and Venus by Scott S. Sheppard et al. on Wednesday 14 September We are conducting a survey using twilight time on the Dark Energy Camera with the Blanco 4m telescope in Chile to look for objects interior to Earth's and Venus' orbits. To date we have discovered two rare Atira/Apohele asteroids, 2021 LJ4 and 2021 PH27, which have orbits completely interior to Earth's orbit. We also discovered one new Apollo type Near Earth Object (NEO) that crosses Earth's orbit, 2022 AP7. Two of the discoveries likely have diameters greater than 1 km. 2022 AP7 is likely the largest Potentially Hazardous Asteroid (PHA) discovered in about eight years. To date we have covered 624 square degrees of sky near to and interior to the orbit of Venus. The average images go to 21.3 mags in the r-band, with the best images near 22nd mag. Our new discovery 2021 PH27 has the smallest semi-major axis known for an asteroid, 0.4617 au, and the largest general relativistic effects (53 arcseconds/century) known for any body in the Solar System. The survey has detected about 15 percent of all known Atira NEOs. We put strong constraints on any stable population of Venus co-orbital resonance objects existing, as well as the Atira and Vatira asteroid classes. These interior asteroid populations are important to complete the census of asteroids near Earth, including some of the most likely Earth impactors that cannot easily be discovered in other surveys. Comparing the actual population of asteroids found interior to Earth and Venus with those predicted to exist by extrapolating from the known population exterior to Earth is important to better understand the origin, composition and structure of the NEO population. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.06245v1

A team led by Carnegie’s Scott S. Sheppard has found 20 new moons orbiting Saturn. This brings the ringed planet’s total number of moons to 82, surpassing Jupiter, which has 79.

Today, astronomers announced the discovery of 12 new moons around Jupiter. Inverse writer Matthew Phelan sat down with the Carnegie Institute’s Scott S. Sheppard who led the team that located the Jovian moons to tell us what this means for our solar systems and why one of the moons is especially odd. Two of the new dozen were uncovered in the spring of 2017 by Sheppard’s team bringing Jupiter’s moon count to 69 (nice), which means we now know there are 79 moons orbiting Jupiter. Questions Include: How did we find these new Jovian moons and why was it a serendipitous finding? What is the criteria that determines whether or not an object is a moon? How many new moons around Jupiter did we find? How do we detect new moons? What are Trojan asteroids? What are prograde and retrograde moons? What is this new “oddball” moon Valetudo and why is it different? Will there be more moons discovered around Jupiter? Is there a minimum size for a moon? What do retrograde and prograde objects tell us about the formation of our solar system? How do moons in our solar system get their names?Follow ‘I Need My Space’ on Social Media:Twitter: @INeedMySpacePodInstagram: @INeedMySpacePodFB Group: I Need My Space PodTo continue the conversation from this episode, use the hashtag #INeedMySpaceFollow Dr. Scott S.

Planet Nine is a hypothetical large planet in the far outer Solar System, the gravitational affects of which would explain the unusual orbital configuration of a group of trans-Neptunian objects (TNOs) that orbit mostly beyond the Kuiper belt. The hypothesis first took form in a 2014 letter to the journal Nature by astronomers Chad Trujillo and Scott S. Sheppard, who had inferred the possible existence of a massive planet from similarities in the orbits of the distant trans-Neptunian objects Sedna and 2012 VP113. On 20 January 2016, researchers Konstantin Batygin and Michael E. Brown at Caltech argued that a massive outer planet would be the likeliest explanation for the similarities in orbits of six distant objects. The predicted planet would be a super-Earth, with an estimated mass of about 10 times that of Earth (approximately 5,000 times the mass of Pluto), a diameter two to four times that of Earth, and a highly elliptical orbit that is so far away that it could take around 15,000 years to orbit the Sun. On the basis of models of planet formation that might include planetary migration from the inner Solar System, such as the fifth giant planet hypothesis, the authors suggest that it may be a primordial giant planet core that was ejected from its original orbit during the nebular epoch of the Solar System’s evolution.
