Origin of the Solar System
This suggests that the solar system formed when small solid particles and dust in space gradually came together through accretion.
Accretion Hypothesis
According to National Aeronautics and Space Administration (NASA) a ____________ is a large heavenly body that orbits the Sun.
Planet
It is a type of space technology
that needs human for it to
function.
Crewed Space Technology
This is a habitable location in space where astronauts and scientists reside whenever they are in space.
Space Stations
Space Stations are also known as?
Space Laboratories
This hypothesis suggests that our solar system were formed from a rotating cloud of gas and dust that flattened into a protoplanetary disk, where the Sun formed at the center and the planets developed from the remaining material.
Nebular Hypothesis
It orbits around the star, its celestial body is roughly spherical in shape, and its shape is relatively smaller than the planets.
Dwarf Planets
These are tools and equipment used by scientists that are not manned that sends data to the scientists in laboratories that are based in the Earth.
Uncrewed Space Technology
It is a man-made instrument that is launched into Earth's orbit. These equipment vary in size, location,
and function.
Artificial Satellite
What does lander carry to move around the targeted heavenly body?
Rover
This idea suggests that the planets were formed when another star passed close to the Sun and pulled out gas that became the planets.
Encounter Hypothesis
Often called as "dirty snowballs"
Comets
This is a vehicle that can either be crewed or uncrewed that travels through space.
Spacecraft
__________ are vehicles in space that astronauts use whenever they are traveling short distances from the space station.
Space Pods
a vehicle that carries scientific instruments to distant objects in space.
Space Probe
Small solid particles collided and stuck together to form larger bodies called __________.
Planetisimals
What is the difference between meteoroids, meteors, and meteorites?
Meteoroids - Located at space
Meteors - Enters the Earth's atmosphere
Meteorites - Reached the Earth's surface
Reusable spacecraft is also known as?
Space Shuttle
________ are useful in studying the
atmosphere of the gas giants.
Probes/Space Probes
Artificial Satellite located around 200 to 2,000 km from Earth's surface. They travel at a speed of 28,000 km/h and can fully orbit Earth in about 90 minutes.
Low Earth Orbit (LEO)
Explain the step-by-step process of Protoplanet Hypothesis.
1. A large cloud of gas and dust that slowly rotated in space. The cloud flattened into a protoplanetary disk
2. Gravity causes small solid particles to collide and stuck together forming the planetisimals.
3. Lastly, the continuous collision caused planetisimals to be the protoplanets (early version of our modern planets).
What are the three conditions to be considered as planet according to NASA.
1. It must orbit a star.
2. It must be big enough to have enough gravity to force it into a spherical shape.
3. It must be big enough that its gravity clears away any other objects of a similar size near its orbit around the Sun.
an uncrewed spacecraft designed to enter the orbit of another heavenly body in space.
Orbiter
Artificial Satellite located at around 20,000 km and orbits the planet in 12 hours.
Medium Earth Orbit (MEO)
Differentiate orbiters and landers
Orbiters monitors the changes in atmosphere and surface of the target heavenly body. While landers, land in the surface of the target heavenly body and used to collect soil, dust, and rock samples.
