- These models of the Sun and its orbiting planets are located next to the Reykjanesvirkjun geothermal power plant in the Reykjanes peninsula in Iceland. The planets size and distance from the model of the sun are proportionally accurate to the actual sun and planets. When this video was published there were only two months until NASA's Perseverance rover was set to land on Mars.
Information about the sun and the planets is from Space Engine, a 3D astronomy program and game engine:
00:10 - Sol, or the Sun, is the star at the center of the Solar system. It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields. It has a diameter of 1,392,684 km, about 109 times that of Earth, and its mass accounts for about 99.86% of the total mass of the Solar System. Chemically, about three quarters of the Sun's mass consists of hydrogen, while the rest is mostly helium. The remainder consists of heavier elements, including oxygen, carbon, neon and iron, among others.
01:33 - Mercury is the innermost planet in the Solar system. It is also the smallest, and its orbit is the most eccentric. It orbits the Sun once in about 88 Earth days, completing three rotations about its axis for every two orbits. The planet is named after the Roman god Mercury, the messenger to the gods.
03:40 - Venus is the second planet in the Solar system, and the second-largest of the terrestrial (rocky) planets. It is the most similar planet in the Solar system to Earth in terms of size and bulk composition. It also has the most circular orbit of any planet and orbits the Sun in about 224.7 days. Its carbon dioxide atmosphere is extremely thick and creates a greenhouse effect strong enough to make Venus the hottest world in the Solar system, with a surface temperature exceeding 735 K (462 [deg]C). Venus is entirely covered with a thick layer of bright sulfuric acid clouds. Abundant lightning has been recorded in the atmosphere. The planet has a very slight axial tilt but has a retrograde rotation, and completes just one rotation in over 243 days. Its rotation is the most anomalous of all the major planets. The surface of Venus has been largely shaped by volcanic activity which likely continues today.
04:38 - Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets. It is sometimes referred to as the World, the Blue Planet, or by its Latin name, Terra. Astronomical symbol is [EARTH].
Earth formed 4.54 billion years ago, and life appeared on its surface within one billion years. The planet is home to millions of species, including humans. Earth's biosphere has significantly altered the atmosphere and other abiotic conditions on the planet, enabling the proliferation of aerobic organisms as well as the formation of the ozone layer which, together with Earth's magnetic field, blocks harmful solar radiation, permitting life on land. The physical properties of the Earth, as well as its geological history and orbit, have allowed life to persist during this period. Estimates on how much longer the planet will to be able to continue to support life range from a mere 500 million years, to as long as 2.3 billion years.
07:25 - Mars is the fourth planet in the Solar system and the outermost of the terrestrial (rocky) planets. It has a thin carbon dioxide atmosphere which has slowly been escaping to space for billions of years and is too thin to significantly moderate the planet's climate. Enormous dust storms can grow to cover the entire world. The planet's moderate axial tilt and fairly eccentric orbit yield mild seasons in the north and extreme seasons in the south. Mars has the most Earth-like surface environment of any planet in the Solar system, with average temperatures in many locations comparable to Antarctica. Mars has extensive sheets of water-ice on and just below much of the surface, and small amounts of liquid water may occasionally flow in some locations. Mars shows evidence of having had a warmer and wetter past in which water flowed across much of the surface for extended periods. Some of these locations were good environments for life, though it is not known whether such life existed. The surface today, though cold and dry, boasts some of the largest geological features in the Solar system, including a 5000 km rift valley and canyon system, and a 22 km tall and 600 km wide volcano.

feels like im right there in space :)
Great Virtual Tour! :) 😊😊👍👍 Love this!
Great share my friend
Feels like a whole different world 😍 I love it
Nice and curious place!!
I didn't know about this video and place. So relaxing song, I liked it^^
And you can go even further and see the outer plantets of the solar system but I didn't have the time. Neptune was an extra hour of walking.
That is so rad! Loved the ambient soundtrack too...well done! Thanks for sharing!😁
Thanks Hendo I'm glad you liked the soundtrack. I wanted to try something different for this video.
beautiful video👍👍
¡Amazing!
Wonderful as always 🥰🙏❤️. Nice background music 🎵.
Thanks Steve I usually don't use music but I'm glad you like it.
IcelandHotSpots oh yes i do 🥰. Are you from Iceland 🇮🇸 ? I mean are you living there? I really like a particular city in Iceland called Akureyri 👌
Yes I've lived here all my life. I did a tour in Akureyri last summer, it's one of my favourite towns.
IcelandHotSpots wonderful 🇮🇸. As soon as i can, i all willing to travel to Iceland and visit this magnificent country. I have bought “natural Skyr” today... wow it’s so tasty 😋. Do you know where it’s made ? I mean... Which part of the country ?
Aww beautiful place. I don't mind the music but I prefer your other videos where you can hear footsteps and nature 🤗
Thanks Df Golez that is good to know 🙂
Thanks for the information, it is good to know that Mars is not so far away from Gunnuhver *LOL* I'll take a look next time :)
Yeah it's lot of fun seeing the planets and you can actually go even further and see the rest, jupiter, saturn, uranus and neptune. I wanted to go see them all but... common I just went to Mars I was exhausted.
@@IcelandHotSpots but you spent less money than N.A.S.A. hahaha
feel to walk on lava moss field 👍👌
0:10 - regular Icelandic orange? And in Siberia, oranges are smaller.
Haha yes they are huge and grow in the ground ☺️
Great, great video...I wonder if the outer planets are also included.
They are! The gas giants are beyond this point but it would have taken me all day to get to Neptune.
@@IcelandHotSpots Haha that's what I thought...Neptune be like either near the airport or the Blue Lagoon. 😅
