Volcanoes on Jupiter
27. Certainly one of Jupiter’s moons, Io, has volcanic eruptions that attain the extent of the Moon. The yearly outbursts are attributable to the gravitational affect Jupiter has on it and should final for a month. Io consistently erupts sulfur and liquid basalt to offer it that particular yellow shade.
Mars – the Pink Planet!
28. Mars is produced from crimson supplies, which is why it’s referred to as the Pink Planet. An abundance of iron minerals and dirt is why every little thing on Mars is crimson.
A large volcano on Mars
29. Olympus Mons, a volcano on Mars, is 100 instances bigger than the one in Hawaii. Specialists imagine it grows that enormous due to the weaker gravity of the Pink Planet.
30. Borealis Basin is likely one of the largest craters on Mars and covers about 40 % of the floor of the crimson planet. It is usually the most important influence crater within the photo voltaic system. In keeping with consultants, it was attributable to a single meteor influence.
Bigger than the Grand Canyon
31. A valley throughout the center of Mars is many instances bigger than the Grand Canyon. The Valis Marines canyon is at 2500 miles, about ten instances the dimensions of the most important on Earth.
Weak gravity
32. Due to the weaker gravity of Mars, it is possible for you to to leap 3 times larger than on Earth. This reality will make people tremendous beings who can leap larger and additional, very like flying for brief distances.
Venus!
33. Venus and Uranus are the one two planets in our photo voltaic system that don’t rotate in the identical route. Uranus rolls on its aspect, and Venus spins clockwise. You may see Venus together with your naked eyes simply after sundown or earlier than daybreak.
Tilt of greater than 90 levels

Clouds of acid
35. The clouds on Venus comprise drops of sulfuric acid, making it unimaginable to see the floor of the planet. What this implies is that at larger altitudes, there’s acid rain current on the planet. It additionally has fixed horrible climate.
A large continent
36. There was once solely one large continent within the heart of the Earth often known as Rodinia till about 250 to 500 million years in the past. The approaching collectively of the continents occurred a second time about 250 million years in the past, forming Pangaea however splitting aside once more.
On the fringe of the Photo voltaic system
37. New proof has been found that there could certainly be a ninth planet. The invention was made in January 2015 {that a} large planet is likely to be on the photo voltaic system’s edge.
Neptune!
38. Neptune is about 30 instances farther from the Solar than the Earth. This planet will get far much less warmth and lightweight however radiates extra warmth than it receives (Neptune seems to have an inner warmth supply.)
Van Allen Belts
39. A number of bands of magnetically trapped particles had been found in 1958, often known as the Van Allen Belts. The invention of those belts helped scientists make higher predictions about area climate.
Jupiter’s crimson spot
40. In keeping with scientists, the good crimson spot on Jupiter was created by a colossal storm. That spot has been shrinking because it was noticed about 150 years in the past.
Planet recognizing!
41. As a result of Jupiter is likely one of the brightest objects in our a part of area, it may be seen with the bare eye from Earth. That’s if yow will discover a great remark level. You may even spot its moons with a telescope or binoculars.
One unusual moon
42. One of many strangest moons within the photo voltaic system, Marinda, was noticed in 1986 by Voyager 2. The gravitational pull of Uranus, its mother or father planet, could have brought on the scarred floor of this Moon. Curiously, the moon was named after “Miranda” from William Shakespeare’s play “The Tempest.”
Why Blue?
43. One of the excellent information about Uranus is the blue shade of this planet. The blue shade is due to the methane in Uranus’s ambiance. The planet absorbs the crimson mild from the Solar however displays the blue mild into area.
The Moon vs Mercury
44. Mercury is the planet that orbits the closest to the Solar in our photo voltaic system. It is usually the smallest planet on this star system and is barely larger than the Earth’s Moon.
The telltale indicators
45. Mercury’s floor is pockmarked with craters, which counsel that it was bombarded with meteor impacts. Many of the marks on the planet’s floor are nonetheless seen as a result of there isn’t a climate on Mercury. The craters on Mercury are a bit totally different than these discovered on the moon’s floor.
The most well liked planet
46. The most well liked planet in our photo voltaic system is Venus, and it is usually the second planet from the Solar. The ambiance of Venus is crammed with carbon dioxide and traps warmth on the planet.
and the farthest!
47. The ice large Neptune is the farthest of all of the planets in our photo voltaic system from the Solar. The blue gasoline planet is about 58 instances the dimensions of Earth, with 17 instances the mass. As a result of it’s so far-off from Earth, the planet can solely be seen with the assistance of a robust telescope.
48. The primary one who ever noticed Neptune is probably Galileo, however he was not credited for the invention at first. Drawings of the planet had been later found amongst his issues, however he didn’t acknowledge it as a planet.
In the identical orbital aircraft
49. All planets, asteroids, and different our bodies in our photo voltaic system orbit across the Solar. Curiously, all these objects journey in the identical orbital aircraft in a flat disc form.
Life!
50. In our photo voltaic system, the Earth is the one planet that helps life so far as we all know. Different planets in our system are too scorching or chilly for all times to exist.
51. Coral reefs discovered within the oceans of the Earth could appear like rocks, however they’re truly alive and are categorised as animals. As a result of they take root on the ocean ground, many individuals thought they had been crops rising within the water.
