Heliocentric/Geocentric
Who was the person that popularized the geocentric model?
Ptolemy
What is the Solar System?
The Solar System is the Sun and everything bound by its gravity, including the eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune), their moons, dwarf planets, and countless asteroids, comets, and other small celestial bodies.
How do they get from their origin to near Earth?
They get to near Earth by being perturbed from their original orbits by the gravitational influence of large planets, particularly Jupiter, which can shift their paths to bring them closer to Earth.
How does inertia related to gravity
Gravity is a force of attraction, while inertia is an object's resistance to changes in motion. They are related because the gravitational mass of an object is numerically equal to its inertial mass
What force holds the Earth in its orbit around the Sun?
The force that holds the Earth in orbit around the Sun is gravity.
Who popularized the Heliocentric model
Copernicus
How many planets are there in the universe?
There are Hundreds of Sextillions of planets
Where do comets come from?
the Kipper Belt, a disk-shaped region beyond Neptune that contains short-period comets, and the much larger, spherical Oort Cloud at the very edge of the solar system, which is the source of long-period comets.
Is gravity an invisible force, or can you perceive it directly?
Gravity is an invisible phenomenon, and we cannot perceive it directly with our senses, but we can detect its effects.
In which direction does the Sun set?
Every day, the Sun, Moon, planets, and stars appear to rise in the east and set in the west
Why did the Heliocentric model replace the Geocentric model?
It replaced the Geocentric model because it provided a more coherent, simpler, and evidence-based understanding of the solar system?
What are the planets of our solar system?
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Is a shooting star a meteor or comet?
It is a meteor.
In what ways do you feel the ``gravity'' of a serious situation?
You "feel the gravity" of a serious situation through a combination of internal, emotional, and physical responses such as a sense of oppression, heaviness, stress, solemnity, and earnestness.
What time of day do you get the shortest shadows?
You get the shortest shadows at local noon because that's when the sun is highest in the sky, and its rays are striking the Earth most directly.
Where is the Heliocentric model located at?
It is located around the sun.
What is the closest planet to the Sun?
Mercury
What are the four types of comets?
Comets are classified into four main categories: Jupiter-family comets (periods < 20 years), Halley-type comets (periods of 20-200 years), long-period comets (periods > 200 years), and interstellar comets (originating from beyond our solar system).
Does gravity shape your day-to-day activities or choices?
Yes, gravity fundamentally and invisibly shapes almost every aspect of your day-to-day activities and choices,
What shape is the Earth?
The Earth is not a perfect sphere, but an oblate spheroid, meaning it is slightly flattened at the poles and bulges at the equator due to its rotation
Who first believed in the Heliocentric model?
Aristarchus of Samos.
What is the closest planet to Earth?
Mercury is the closest to Earth.
What is the difference from comets,meteors,and asteroids.
Asteroids are large, rocky bodies, while comets are icy, dusty bodies that develop tails when near the sun. Meteors are the visible streak of light caused by small pieces of asteroids or comets (called meteoroids) burning up in Earth's atmosphere. A meteorite is a meteoroid that survives the atmospheric entry and lands on Earth's surface.
How does gravity impact space travel beyond Earth's atmosphere?
Gravity impacts space travel by holding celestial bodies together and shaping their paths
How many days does it take the Earth to orbit the Sun?
365 days
