The sun gets bigger and will destroy planets in millions of years. We will probably go extinct.

The sun is currently in its main sequence stage, where it fuses hydrogen into helium. As it ages, it will eventually expand into a red giant, consuming the inner planets, before shedding its outer layers to form a planetary nebula and leaving behind a white dwarf core. This whole process will take billions of years to complete.
As the Sun ages, it will gradually increase in size, brightness, and temperature. This will cause the circle graph representing the Sun to shift towards the higher end of the scale in terms of luminosity and temperature, while the size of the circle may increase slightly. Eventually, the Sun will exhaust its nuclear fuel and evolve into a red giant, causing significant changes in the circle graph.
how does earths distance from the sun change throughout the year
No. Earth's tilt does not change as Earth revolves around the sun.
The Sun's growth rate is not significant to measure in terms of a year. It slowly increases in size over billions of years due to nuclear reactions in its core, gradually expanding as it ages. However, the expansion is not noticeable within a human timescale.
Clouds can change shape and get light from the sun when they pass in front of it, causing shadows to form on the ground.
