Solar System

(Statistical Information)

These facts provide valuable insights into the characteristics and measurements of the Earth, Moon, and Sun, allowing us to better understand their unique properties and relationships within the solar system.

The Earth is approximately 4,600 million years old, as is the Moon. The Sun, on the other hand, is estimated to be around 5,000 million years old.

The average speed of revolution for the Earth is about 30 km/sec, while the Moon revolves around the Earth at a speed of 1 km/sec. The Sun, being a star, has a much faster revolution speed of 250 km/sec.

When it comes to brightness, the Earth does not have a specific unit of brightness associated with it. However, the Moon has a brightness equivalent to 1 unit, and the Sun shines with an astonishing brightness of 5,00,000 units.

The Moon is located at an average distance of 3,84,000 km from the Earth, while the Sun is much farther away at a distance of 150 million km.

In terms of light travel time, it takes about 1.25 seconds for Moon rays to reach the Earth, whereas sunlight takes approximately 8 minutes and 19 seconds to reach us.

If we consider the speed of a rocket flying at 12 km/sec, it would take approximately 9 hours to reach the Moon and about 5 months to reach the Sun.

The equatorial diameter of the Earth is approximately 12,757 km, whereas the Moon has a much smaller diameter of 3,476 km. The Sun, being a star, has a significantly larger diameter of around 13,52,000 km (rounded).

The major gases that make up the Earth's atmosphere are Nitrogen and Oxygen. In contrast, the Moon does not possess any significant gases, while the Sun primarily consists of Hydrogen and Helium.

The Earth takes about 365 days, 5 hours, 48 minutes, and 46 seconds to complete one revolution around the Sun. The Moon, with reference to the Sun, completes one rotation and revolution simultaneously in approximately 29 and a half days. The Sun, being a star, has a much longer revolution time of 225 million years.

The Earth takes about 23 hours, 56 minutes, and 4 seconds to complete one rotation on its axis. Similarly, the Moon, with reference to the Sun, completes one rotation and revolution in approximately 29 and a half days. The Sun, being a star, rotates about its own axis in about 25 days.

The surface temperature on Earth varies, with an average temperature of about 15°C. On the Moon, the temperature ranges from approximately 100°C to 127°C during the day and drops to as low as -150°C to -183°C during the night. The outer layer of the Sun reaches an incredibly high temperature of around 6,000°C.

In terms of volume, if we consider the Earth as one unit, the Moon's volume is approximately 1/49th of the Earth's volume. The Sun, being a star, has a much larger volume of about 13,00,000 times that of the Earth.

This table provides a comparison of various characteristics of different planets in our solar system. It includes information such as the average distance from the sun, diameter, duration of rotation and revolution, number of satellites, average temperature, speed of revolution, and date of discovery for each planet.

It takes about 59 days for Mercury to complete one rotation and 88 days to revolve around the sun. It does not have any known satellites. The average temperature on Mercury varies between 4300°C on the side facing the sun and -1700°C on the side not facing the sun. Mercury was discovered in prehistoric times.

Venus is situated approximately 108.2 million km away from the sun and has a diameter of 12,100 km. It takes around 243 days for Venus to complete one rotation on its axis and 225 days to orbit the sun. Venus does not have any known satellites. The average temperature on Venus is about 4700°C. It was discovered in prehistoric times.

Earth is located at an average distance of 149.6 million km from the sun and has a diameter of 12,757 km. It takes approximately 23 hours, 56 minutes, and 4 seconds for the Earth to complete one rotation on its axis, and 365 days, 5 hours, 48 minutes, and 46 seconds to revolve around the sun. The Earth has one satellite, which is the Moon. The average temperature on Earth varies, but the average is around 15°C. Earth was discovered in prehistoric times.
