The amount of light energy gathered by a telescope is determined by the size of its objective lens. The larger the lens’s surface area, the better the telescope can observe faint luminous objects. When light passes through the objective lens of a refractor telescope, it is refracted and forms an image of the object in…
The solar system is comprised of the Sun and all celestial bodies that orbit around it due to its gravitational pull. Nicolaus Copernicus (1473-1543), a Polish astronomer, is known for developing the heliocentric model of the universe. Copernicus’ theory of the solar system posited that the Sun was at the center, with the planets orbiting…
The atmosphere is composed of a combination of 9 essential gases that encompass the Earth’s surface. This mixture of gases forms the air, providing the necessary conditions for the sustenance of living organisms. Which gases make up the Earth’s atmosphere? As mentioned previously, the composition of the Earth’s atmosphere is not uniform – it consists…
Mercury is the tiniest planet in our solar system. It is categorized as one of the terrestrial planets, and its physical characteristics bear a striking resemblance to that of the Moon.

Saturn, the sixth planet in our solar system, is known for its unique internal structure. It is the second largest planet, after Jupiter, in terms of size among all the planets orbiting the Sun. Scientists categorize Saturn as a gas giant, a type of planet composed mainly of hydrogen and helium. The planet was named…
The sideric orbital period (derived from the Latin word “sidus” meaning star; genitive case “sideris”) refers to the duration in which a celestial satellite completes a full revolution around its main body in relation to the stars. The concept of the “sideric circulation period” is applicable to celestial bodies that orbit the Earth, such as…
