541132 Leleākūhonua (/ ˌ l ɛ l eɪ ɑː ˌ k uː h oʊ ˈ n uː ə /) (provisional designation 2015 TG 387) is an extreme trans-Neptunian object and sednoid in the outermost part of the Solar System.
S/2015 (136472) 1, unofficially nicknamed MK2 by the discovery team, [2] is the only known moon of the trans-Neptunian dwarf planet Makemake. [1] [4] It is estimated to be 175 km (110 mi) in diameter and has a semi-major axis of at least 21,000 km (13,000 mi) from Makemake. [1] Its orbital period is at least 12 days if it has a circular orbit.
Makemake [e] (minor-planet designation: 136472 Makemake) is a dwarf planet and the largest of what is known as the classical population of Kuiper belt objects, [b] with a diameter approximately that of Saturn's moon Iapetus, or 60% that of Pluto. [24] [25] It has one known satellite. [26]
A sednoid is a trans-Neptunian object with a large semi-major axis and a high perihelion, similar to the orbit of the dwarf planet Sedna. The consensus among astronomers is that there are only three objects that are known from this population: Sedna, 2012 VP 113, and 541132 Leleākūhonua (2015 TG 387). [1] All three have perihelia greater than ...
Because Sedna and 2002 MS 4 have no known moons, ... 0.2 0.0204 dwarf planet; plutino; binary: 2004 Sedna 90377: ... Makemake I: ≈ 80: moon of Makemake [141]
One particularly distant body is 90377 Sedna, which was discovered in November 2003.It has an extremely eccentric orbit that takes it to an aphelion of 937 AU. [2] It takes over 10,000 years to orbit, and during the next 50 years it will slowly move closer to the Sun as it comes to perihelion at a distance of 76 AU from the Sun. [3] Sedna is the largest known sednoid, a class of objects that ...
The orbits of Sedna, 2012 VP 113, Leleākūhonua, and other very distant objects along with the predicted orbit of Planet Nine [A]. An extreme trans-Neptunian object (ETNO) is a trans-Neptunian object orbiting the Sun well beyond Neptune (30 AU) in the outermost region of the Solar System.
Since the National Geographic competition, two additional bodies were designated as dwarf planets, Makemake and Haumea, on July 11 and September 17, 2008 respectively. A 2015 New York Times article suggested some mnemonics including, "My Very Educated Mother Cannot Just Serve Us Nine Pizzas—Hundreds May Eat!"
