SUnknownHow Big is the Biggest Galaxy in the Universe?

Tue, Jul 11, 2017

The Milky Way is a large galaxy thought fair typical for a spiral galaxy. Our nearest spiral neighbor Andromeda is probably twice as large. When spiral galaxies merge they for enormous elliptical galaxies with the largest known being IC-1101. It is large enough to engulf the entire local from of the Milky Way, Andromesda, the Mangelanic clouds and Traiangulum galaxies.

SUnknownHaumea - The Egg Shaped World (Beyond Pluto Episode 1)

Sun, Nov 18, 2018

Dwarf planet Haumea is a Kuiper Belt object a bit farther from the sun than Pluto. Like Pluto it has a deep red spot probably due to tholins created by solar energy reacting with methane on its surface. Haumea is one of the fastest rotating objects in the Solar System giving it an egg shape, has two moons and an icy ring all perhaps caused by a impact in the past.

SUnknownMakemake - The Icy Red World (Beyond Pluto Episode 2)

Mon, Dec 10, 2018

Dwarf planet Makemake is a Kuiper belt object a bit smaller than Pluto. Like Pluto it is thought its surface is composed of frozen nitrogen and methane which reacts with solar radiation to produce tholins that give it a reddish brown hue. Makemake has its own moon provisionally name Mk2.

SUnknownSedna - The Oort Cloud Dwarf Planet (Beyond Pluto Episode 4)

Thu, Jul 04, 2019

Sedna is an object in the outer Solar system so distant is presumed to be a Oort cloud object. It is thought to be large enough to classify as a dwarf planet and is to have surface tholins like most known Kuiper belt objects. It is currently on an inbound trajectory reaching perihelion in 2075 when it will be three times farther from the sun than Neptune.

SUnknownGonggong - The Largest Unnamed World in the Solar System

Wed, Aug 07, 2019

GongGong is the seventh dwarf planet discovered. It is thought to be an icy rock world and like other Kuiper Belt objects it has a reddish surface likely due to tholins. It's rotation rate of 45 hours is unusually long. It has it's own moon (Xiangliu) unnamed at the time of this production.

SUnknownThe Goblin Dwarf Planet - An Inner Oort Cloud Object

Tue, Oct 29, 2019

The Golblin, discovered in 2009, is believed to be a dwarf planet and Oort Cloud object about 200 miles in diameter with a orbital period of 32,000 years. It is currently inbound to the Solar System but will never come even close to the orbit of Pluto. But it may be helpful in the search for the hypothetical Planet Nine.

SUnknownMercury 101: A World of Extremes

Wed, Apr 08, 2020

Mercury is a cratered rocky planet similar to the other terrestrial planets with an outer crust, mantle, liquid outer core and solid inner core but lacking an atmosphere. Due to proximity to the sun it is a challenge to observe but was visited by two probes with a third due to visit in 2025.

SUnknownExtremely Rare Planet Discovered, a Cloudless Jupiter!

Wed, Feb 03, 2021

Planet Wasp 62b is a hot Jupiter class planet, half again as large of Jupiter though less massive and orbiting close to its parent star. Astronomers studying the planet observed spectral lines for sodium which is smoking gun evidence that it has a rare cloudless as contrasted with Jupiter's dense clouds.

SUnknownTriton: Neptune's Backwards Moon Was Once a Dwarf Planet Larger than Pluto!

Wed, Feb 17, 2021

Neptune'n moon Triton is an oddball. In contrast to all other major moons in the Solar System it has an inclined retrograde orbit relative to Neptune. And, geologically it is more like a Kuiper Belt object. If so, it is the largest know Kuiper Belt object and it probably eliminated several of Neptune's existing moons when it was captured.
