Insight A System - 3rd Planet (Insight A-III)

Insight A-III is the third planet orbiting Insight A. It is a hot Ice-giant orbiting it’s sun at an average distance of 0.12 AU. The planet’s atmosphere has a temperature of 960 F and it’s atmosphere lacks any type of define cloud decks. This is a helium ice giant, meaning that it has lost all of it’s hydrogen and the atmosphere is dominated by helium instead. As a result, the planet has a monochromatic color.

Insight A-III has a mass of 13.22 Earths, and a diameter of 4.03 times that of Earth. The planet is tidally locked to it’s sun and orbits the sun once every 14.76 Earth days.

Another Earth-Like world I have come across in the Large Magellanic Cloud Galaxy. This one has two moons and a rather cold surface with lots of ice covered mountains.

Triangulum Log - Vernier System.

We’ve gone deeper into the Triangulum System and come across this binary system. The system consists of a hot F-Type Star 3.1 times brighter than our sun, orbited by a much less luminous K-Type Star only a fifth the brightness of our sun. The system has 6 planet’s including the most earth-like planet I’ve come across yet.

The Inner-most planet is a warm Ice-Giant with 53 earth masses and atmosphere temperatures of 378 K or 221 °F, orbiting the common center of mass of the two suns at a distance of 0.78 AU. The atmosphere of the planet is extremely turbulent under the intense sun-light. Wind speeds reach up to 1,100 kilometers per hour and cyclonic systems churn across the equator.

The second planet is Earth-like planet roughly 0.20 Earth masses, and radius 0.60 times that of Earth. Liquid water oceans cover a small portion of the surface. The planet is more desert-like than Earth, with water covering less than 15% of the surface. The atmosphere has only 0.15 atmosphere’s of pressure and has an unusual composition. Carbon dioxide comprises 84.4% of the atmosphere mixed with 13.1% Acetylene and 1.3% sulfur dioxide. The acetylene is stable in the atmosphere due to there being no oxygen; however, ultraviolet light natural breaks the compound down, forming Tholins in the atmosphere, giving the atmosphere a thick haze. Surface temperatures average 320 K or 116 °F. The planet has no polar ice-caps and orbits 1.25 AU from the stars. Several asteroid-sized moons orbit the planet along with larger rounded satellite that has a radios of 374 km.

Tumblr Changes - My Thoughts

I know this post is not about space and astronomy, but I wanted to voice my thoughts about the upcoming ban on Tumblr and how the automatic algorithms are going to affect everyone on there.

First off, I do not post or follow any NFSW Tumblr, so the primary ban does not affect either my Space Engine Tumblr or Rabbit and Shark Tumblr or other Tumblr’s that I follow in that regard, but the algorithms Tumblr has created are already beginning to affect my space engine posts. I mean seriously, how are my pictures of planets, alien landscapes and nebulas being flagged as adult material?

I understand that there are nearly 450 million users on here, but Tumblr has just 400 or so employees and for their employees to go through perhaps billions of images is not practical so they had to write a program to do the work for them. Auto-flagging images however, is a major problem for us non-NFSW Tumblrs, and we are only just now seeing the start of this problem. Eventually it is going to get to the point that we all have to wait weeks even months for our “sensitive marked” pictures to be marked as safe, since an actual person will have to review it.

Final conclusion. This ban and the way it is being implemented is a bad idea, and to be honest I also think an assault on free speech. More importantly, Tumblr better fix its auto-identification programs before a lot of us leave out of frustration when pictures of planets, rabbits, and sharks are all marked as adult.

PLEASE SPREAD THE WORD AND REPOST.

O’Sirus System - Post 4 (Rings)

Two planets in the O’Sirus System have rings, the 7th and 10th planets respectively.

The 7th planet is an ice-world with a thick icy crust floating on a sub-surface ocean. It is roughly 0.30 Earth-masses, has a radius 75% that of Earth and orbits 1.32 AU from the sun. The surface has a carbon dioxide atmosphere of approximately the same pressure as the atmosphere of Mars and surface temperatures of 133 K or -224 °F.

The 10th world is small ice giant 10.5 times more massive than Earth, has a radius 2.8 times larger than Earth and orbits at a distance of 6.02 AU. This world also has a pronounced ring system.

Insight B System - Sixth Planet’s (Insight B-VI) Major Moons

Three large terrestrial-sized moons orbit Insight B-VI, all of them being roughly halfway between the size of Mars and Venus. Lunar Stats Below.

Insight B-VI-M2 (Second Moon) Radius = 4,567.71 km (0.72 x Earth) Mass = 0.24 Earth Masses Atmosphere = 0.13 Atmospheres/ Ammonia, Sulfur Dioxide, Methane, and Carbon Dioxide

Insight B-VI-M3 (Third Moon) Radius = 5,672.06 km (0.89 x Earth) Mass = 0.31 Earth Masses Atmosphere = 0.23 Atmospheres/ Carbon Dioxide, Methane and Acetylene

Insight B-VI-M4 (Fourth moon) Radius = 5,786.11 km (0.91 x Earth) Mass = 0.40 Earth Masses Atmosphere = 0.01 Atmospheres/ Methane, Carbon Dioxide and Nitrogen
