Fact about ‘Pluto’


 Pluto takes the longest time of the eight planets (248 Earth years) to orbit around the sun. Because it’s the closest to the sun, Mercury has the fastest orbit, at 88 Earth days. Earth takes 365 days to orbit the sun.

Pluto is the only known dwarf planet with an atmosphere. It is very thin and would be toxic for humans to breathe. When Pluto is at its perihelion (closest to the sun), Pluto’s atmosphere is gas. When Pluto is at its aphelion (farthest from the sun), its atmosphere freezes and falls like snow.

Facts About The Moon







Diameter: 3,475 km
Mass: 7.35 × 10^22 kg (0.01 Earths)
Orbits: The Earth
Orbit Distance: 384,400 km
Orbit Period: 27.3 days
Surface Temperature: -233 to 123 °C

The dark side of the moon is a myth.
In reality both sides of the Moon see the same amount of sunlight however only one face of the Moon is ever seen from Earth.

The side facing away from Earth has only been seen by the human eye from spacecraft.

About Supernova


1. Approximately one supernova occurs every second. Supernovae happen more often than you might think: one occurs somewhere in the universe every second. However, the Milky Way only has an average of two supernovae per century and trying to spot one as it happens is still very tricky. The last one directly observed in our galaxy was over 400 years ago and its namesake, Johannes Kepler, considered SN 1604 a new type of star at the time.

2. Most chemical elements are made in a supernova. The normal process inside stars, stellar nucleosynthesis, fuses hydrogen to create the elements, from helium through the periodic table to iron. To create the heavier elements through to uranium, however, requires something exponentially hotter and more energetic even than the core of a star – those forces typically found in the instant of a supernova.
