ice granules

Saturn’s rings are made mainly of ice particles. These icy particles are small fragments orbiting Saturn, consisting of mixtures of ice and rock. Although Saturn’s rings are extremely thin, they extend over a vast area, and through a telescope they can be seen in a very beautiful form.

Summer Triangle

The three stars Vega, Altair, and Deneb are called the Summer Triangle. These stars are very bright in the summer night sky and form a triangle. Vega is the prominent star of Lyra, Altair of Aquila, and Deneb of Cygnus, and the large triangle they create stands out in the summer night sky, making it well loved by many people.

380,000 km

The distance from Earth to the Moon is about 380,000 km. This is the average distance between Earth and the Moon, and because the Moon’s orbit is elliptical, the actual distance varies somewhat. The Moon is the closest celestial body to Earth, and the glow we see in the night sky reaches us from this distance.

200 billion

There are about 200 billion stars in the Milky Way. The Milky Way is the galaxy we live in, and these stars are scattered across a vast space, some of which we can see in our night sky. The stars of the Milky Way vary in age and size, and their number is astonishing in scale.

8 minutes 30 seconds

It takes about 8 minutes and 30 seconds for light emitted from the Sun to reach Earth. This is the time required for light, traveling at approximately 300,000 km per second, to cover the roughly 150 million kilometers between the Sun and Earth. Because of this delay, when we look up at the Sun, we are actually seeing it as it was 8 minutes and 30 seconds ago.

100 times the Earth

The Sun is about 100 times the size of Earth. Its diameter is approximately 1.39 million kilometers, which shows its immense scale compared to Earth’s diameter of about 13,000 kilometers. The Sun is at the center of the solar system, emits a tremendous amount of energy, and is essential for supporting life on Earth.

about 6000 degrees

The surface temperature of the Sun is about 6,000 degrees. This high temperature is due to the energy produced by the nuclear fusion reactions the Sun undergoes, which provide light and heat to our Earth. At the Sun’s core, the temperature is even higher, reaching about 15 million degrees.
