Meteoroid vs. Asteroid
Meteoroids and asteroids are both small rocky bodies that orbit the Sun. However, there are some key differences between the two.
- Size: Meteoroids are smaller than asteroids, with diameters ranging from a few millimeters to a few meters. Asteroids, on the other hand, can be up to hundreds of kilometers in diameter.
- Composition: Meteoroids are composed of rock and metal, while asteroids are composed of a variety of materials, including rock, metal, and ice.
- Origin: Meteoroids are believed to be fragments of asteroids or comets that have broken apart as a result of collisions. Asteroids, on the other hand, are believed to be remnants of the solar system’s early formation.
- Occurrence: Meteoroids are much more common than asteroids, with millions of meteoroids hitting the Earth’s atmosphere every year. Asteroids, on the other hand, are much less common, with only a few thousand known asteroids orbiting the Sun.
How to Identify a Comet
- A bright spot (nucleus): Comets appear as a bright, fuzzy spot of light in the night sky. This is the comet’s nucleus, composed of ice, dust, and rocky materials.
- A tail: Most comets have a tail that trails behind the nucleus. The tail is made of gas and dust particles blown away from the comet by the sun’s radiation.
- Motion: Comets move across the sky, typically at slower speeds than other celestial objects. Observing the comet’s position over several nights can help confirm its movement.
- Distance: Comets can be seen with the naked eye or binoculars when they are relatively close to Earth. However, some comets are only visible through telescopes if they are farther away.
- Orbital characteristics: Comets typically have highly elliptical orbits around the sun. As they approach the sun, their tails become more pronounced.
Astronomy for Beginners
Astronomy, the study of celestial objects and phenomena, is an exciting field that explores the vastness of the universe. For beginners, understanding the basics can set the foundation for further exploration:
- Celestial Bodies: Astronomy examines various celestial bodies, including stars, planets, moons, asteroids, comets, and galaxies.
- Types of Stars: Stars vary in size, color, and temperature, with the Sun being our closest star.
- Planetary Systems: Solar systems, like our own, consist of a central star and orbiting planets.
- Telescopes: Telescopes allow astronomers to observe distant celestial objects by magnifying their light.
- Constellations: Stars are often grouped into constellations, recognizable patterns in the night sky.
- The Milky Way: Our galaxy, the Milky Way, is a vast collection of stars, gas, and dust.
- Cosmology: Cosmology investigates the origin, evolution, and future of the universe, including theories such as the Big Bang and dark matter.
Supermoon Myths and Legends
Supermoons, when the full moon is at its closest point to Earth, have inspired numerous myths and legends throughout history.
- Native American Legends: Supermoons were believed to bring heightened energy, psychic powers, and spiritual insight. Some tribes also associated them with good harvests, fertility, and abundance.
- Greek Mythology: The goddess Selene, known as the "Queen of the Night," was said to ride a chariot pulled by white horses across the sky during a supermoon.
- Hinduism: The full moon is considered an auspicious time for religious ceremonies and rituals. Supermoons are believed to amplify these effects, bringing blessings and positive energy.
- Chinese Folklore: Supermoons are known as "Full Goat Moons" and are associated with happiness, prosperity, and good fortune. They were often celebrated with festivals and fireworks.

Draconids Meteor Shower 2024
The Draconids meteor shower is an annual celestial event that occurs from October 6th to 10th with a peak on October 8th.
The shower is caused by debris from the comet 21P/Giacobini-Zinner, which orbits the Sun every 6.6 years. When the Earth passes through the comet’s debris trail, small particles enter the atmosphere and burn up, creating the visible meteors.
The Draconids are known for their slow and faint meteors, with an average speed of 20 kilometers per second. The shower typically produces a few dozen meteors per hour, but occasional outbursts can result in thousands of meteors per hour. The best viewing location is under clear, dark skies away from light pollution.
When is the Draconids Meteor Shower?
The Draconids meteor shower occurs annually from October 6th to 10th, and reaches its peak activity around October 8th to 9th. The shower is caused by debris from the comet 21 P/Giacobini-Zinner, which orbits the sun every 6.6 years. The Draconids are known for producing bright, fast-moving meteors, and can produce up to 20 meteors per hour during the peak of the shower.
Supermoon in 2024
A supermoon occurs when the moon is closest to the Earth in its orbit, making it appear larger and brighter than usual. In 2024, there will be four supermoons:
- July 13: This supermoon will be the largest and brightest of the year. It will be visible throughout the night.
