Our Sun is classified as a yellow dwarf star, but it is considered average in size compared to other stars. So, what is the smallest known star in the Universe according to scientists? Let’s explore this question. Although the Sun is classified as a dwarf star, it is not actually small. In fact, it is…

The Earth-Moon distance is vast, yet it pales in comparison to the vastness of space. Space is known to be immense, which is why astronomers use different units of measurement than what we are accustomed to. While kilometers are still useful when measuring the distance to the Moon (384,000 km), they become less practical when…

Out of the many moons that orbit Jupiter, eight are considered to be permanent satellites. These satellites have ProGrade orbits, meaning they move in the same direction as Jupiter’s rotation, and their orbits are nearly circular and not highly inclined with respect to Jupiter’s equatorial plane. The most famous of these satellites are the Galilean…

No individual has experienced 4.5 billion seconds (approximately 143 years), and even the history of our civilization spans only 4.5 billion minutes (around 8560 years). However, the Earth itself has endured for a staggering 4.5 billion years! Throughout its existence, the planet has undergone numerous transformations.

Even without possessing a specialized astronomical device, one can easily comprehend the vast size disparity between Jupiter and Earth. This can be achieved by simply observing visual representations of the colossal celestial body, distinguished by its well-defined edges. Jupiter’s size is difficult to determine due to its unique composition as a gas giant. The constantly…

A light year is a unit of measurement that represents the distance light travels in one year, which is approximately 6 trillion miles. This unit is used to measure the vast distances between objects in space, specifically from Earth to various celestial bodies. advertisement Within our own solar system, the farthest planet visible to the…

The phenomenon of the universe expanding is something that can be observed, as the distances between galaxies and other celestial objects are getting larger as time goes on. This discovery completely changed the way we understand the universe and has become a fundamental idea in modern cosmology. The idea of a universe that is expanding…

The Earth revolves around its own axis in a counterclockwise direction (when viewed from the North Pole). The axis is an imaginary line that passes through the North and South Poles, with the poles themselves being stationary and not participating in the rotation. Meanwhile, all other points on the Earth’s surface are in motion, with…

The Sun’s outermost layers, specifically the atmosphere, are responsible for producing all types of radiation that we detect. The photosphere, which is the deepest and densest layer of the atmosphere, is approximately 200-300 km thick and has a matter density of about 10-5 kg/m3. This density is significantly lower than that of the Earth’s atmosphere,…
