The document provides information about the relative sizes of various planets, moons, stars, and the universe. It notes that over 1,300 Earths could fit inside Jupiter and that several moons like Ganymede and Titan are larger than Mercury and Pluto. While our Sun is large, it is dwarfed by stars like Sirius, Pollux, and Antares. The largest star mentioned, Antares, is over 2,000 times the size of the Sun. The known universe is estimated to be 78 billion light years in size and 13.7 billion years old.
3. How many earth can fit
in the Jupiter?
• Jupiter is so big that all the other planets in
the solar system could fit inside it.
• More than 1,300 Earths would fit inside
Jupiter.
• Jupiter is the fifth planet from the sun
5. Which is larger moon or Pluto?
• However, not all of
he moons are smaller than all of the planets.
There are seven moons in our Solar System,
including our own Moon, that
are larger than Pluto.
• Jupiter's moon Ganymede is the largest
moon in the Solar System, and Ganymede as
well as Saturn's moon Titan are
both larger than Mercury and Pluto

7. Size Difference Between
Sun & Earth
• The Sun is 864,400 miles (1,391,000
kilometers) across. This is about 109 times the
diameter of Earth.
• The Sun weighs about 333,000 times as much
as Earth.
• It is so large that about 1,300,000 planet
Earths can fit inside of it.

9. Size Difference Between
Sun and Arcturus
• Our sun is one of billions in the entire universe.
• It also is fairly small in comparison with other big
stars.
• In fact, our sun is classified as a G2 dwarf star.
Sirius, the brightest star in the night sky, is twice
as massive as the sun and 25 times more
luminous.
• And Sirius is dwarfed by Pollux, which is eight
times the radius of the sun.
• And Pollux is dwarfed by Arcturus, which is
almost 26 times the size of the sun.

11. Sun in comparison to Antares
• But there are bigger stars yet. When
compared to Antares, our handsome sun is a
mere pixel on a map.
• And Antares is not even the biggest star.
• It is about 2,000 times the size of the sun, or
more than twice the size of Antares.
12. How Big is the Universe?
• The Wilkinson Microwave Anisotropy Probe calculated
the age of the known universe at 13.7 billion years
old, based on its radius of 13.7 billion light years.
• And it is growing bigger every day, at a speed of 71
km/s/Mpc.
• The size of the whole universe is estimated to be 78
billion light years.
• If you start traveling today at 60 miles per hour
(100km/h) you’ll get to the end of your first coffee
stop, the end of one light year, in nine trillion years.
• Then you just keep going for another 77.999 999
billion light years. Or you could stay here, look after
our beautiful planet… and enjoy the sun.
