Comets in Our Solar System: The Great January Comet of 1910

The Great January Comet of 1910.

Comets have always interested astronomers due to their unique characteristics, orbital patterns, and their odd appearances in our solar system. Many of the comets have passed our solar system once and will never return or return after thousands of years. Despite not returning in a long while, they are still one of … Read more

Comets in our Solar System-The Great Comet of 1744

A display of 6 tails by The Great Comet of 1744.

Among the numerous comets in our solar system, few are periodic while most of them are non-periodic. Non-periodic means that the comets will no longer return close to the sun in their regular orbit. For this reason, non-periodic comets appear just once and can no longer be seen afterward. One such comet … Read more

The Wild 2 Comet

The Wild 2 Comet

Plenty of comets surround our solar system with some of them being known and active while others are not so active or periodic which is why we know little about them. Some of these comets have been discovered centuries ago as well such as the Halley’s Comet. On the other hand, a … Read more

Halley’s Comet

Comet Halley in 1986.

Our solar system is full of amazing comets that have different objective properties. Many of these comets are periodic which means that they come around every once in a while close to the orbital path of Earth and the sun. At this point, they can be easily spotted as well. One such … Read more

Craters On Earth – Wolfe Creek Crater

Wolfe Creek Crater

Australian Aborigines had long known of the existence of the crater near Wolfe Creek when an aerial survey identified this impact crater in 1947. Wolfe Creek Crater is almost circular and is believed to be the second-largest crater in the world. It is one of the best-preserved impact craters in the world. … Read more

Barringer Crater

Panoramic view of Barringer Crater

In the solar system, impact craters are the dominant geographic features of many solid solar system objects such as the Moon, Ganymede, Callisto, and other small asteroids. Some planets and moons experience surface geological processes such as Earth, Europa, Venus, and Titan. Due to erosion, the impact craters are buried or transformed … Read more
