Answer: c) Planets in our galaxy with radii between Earth and Neptune.

Explanation: Sub-Neptune planets are the most commonly observed type of planets in our galaxy, and they have radii between that of Earth and Neptune.

Answer: b) An orbit around the Earth with an altitude of 22,300 miles.

Explanation: A geostationary satellite is in a specific orbit around the Earth with an altitude of approximately 22,300 miles or 35,800 kilometers. These satellites revolve in the same direction as the Earth rotates, completing one orbit in about 24 hours. The satellite appears stationary from the perspective of someone on the ground, as it moves in sync with the Earth’s rotation.

Answer: b) An orbit around the Earth with an altitude of around 1,200 miles or less.

Explanation: LEO is an orbit around the Earth with an altitude that lies towards the lower end of the range of possible orbits, approximately 1,200 miles (2,000 km) or less. Satellites in LEO, unlike geostationary satellites, do not have a fixed position and can follow various paths. LEO is commonly used for satellite imaging and is also the orbit used for the International Space Station (ISS).

Answer: b) Amazon’s project to build a network of 3,236 satellites in low Earth orbit for high-speed internet access.

Explanation: Project Kuiper is Amazon’s initiative to deploy a constellation of 3,236 satellites in low Earth orbit (LEO) to provide high-speed internet access globally. The project aims to bring fast and affordable broadband to underserved and unserved communities. It consists of ground infrastructure, global networking, satellites in LEO, and customer terminals.
