Read the text, look at the table and do the math

Light travels in a vacuum \approx 299,792 km per second (to ease the recording, this distance is rounded up to 300,000 km per second). During this time, light can circle the Earth along the equator as much as 7.5 times! This distance seems incredibly large for humans, but for the cosmos it is, of course, very small. What distance will light cover in a minute of its travel through the vacuum? To do this, multiply 300,000 km by 60 seconds and the answer will be 18,000,000 km. Similarly, astrophysicists introduced the concept of a "light year", determining how much distance light travels in a vacuum in 12 months.

When completing the task, you will need this table:

Distances between some space objects in kilometers

Sun

Earth

\approx 150 million

Mars

\approx 228 million

Jupiter

\approx 779 million

Neptune

\approx 4.5 billion

Calculate how long it will take for the light produced by one of the luminous objects to reach the other one.

The light emitted by the Sun reaches the Earth in about.

The light emitted by your desk lamp in the evening when turned on will reach Mars (if both planets are on the same side of the Sun) in.

The light emitted by the Sun will take to reach the last planet in the solar system — Neptune.

The largest atmospheric vortex in the solar system is the Great Red Spot on Jupiter, which can be seen with a telescope, but the light transmitting the image will reach the Earth in almost.
