Astronomy Basics

What is the Earth's nearest celestial neighbour?

What is the average distance from the Earth to the Sun?

What is the primary force that governs a tide?

What is the alignment of celestial bodies required for an eclipse to occur?

Which of the following is NOT a type of eclipse?

Light travels at a speed of approximately $299,792,458$ meters per second.

A constellation is a specific pattern of stars that, when connected, forms a shape or figure.

Fixed stars are massive enough to sustain nuclear fusion in their cores, unlike planets.

Aurora borealis is caused by the interaction between the Earth's magnetic field and high-energy particles from the Sun.

Aurora borealis can only be observed near the Earth's equator.

Celestial Bodies and Phenomena

Light travels at a speed of approximately 299,792,458 meters per second.
A constellation is a group of stars that, when connected, form a pattern or shape on the celestial sphere.

Stars and Planets

A fixed star is a celestial body that is stationary relative to the Earth, while a planet is a celestial body that orbits the Sun.

Atmospheric Phenomena

Aurora borealis, also known as the northern lights, is a natural light display in the Earth's polar regions, caused by charged particles from the Sun interacting with the Earth's magnetic field and atmosphere.

The Earth and its Neighbour

The Earth's nearest celestial neighbour is the Moon.
The average distance from the Earth to the Sun is approximately 149.6 million kilometers.

Tides and Eclipses

Tides are governed by the gravitational pull of the Moon and the Sun on the Earth's oceans.
An eclipse occurs when one celestial body passes through the shadow of another, such as the Moon passing through the Earth's shadow during a lunar eclipse, or the Earth passing through the Moon's shadow during a solar eclipse.

Test your knowledge of basic astronomy concepts, including the Earth's nearest celestial neighbor, its distance from the sun, and the causes of tides and eclipses.
