* Smaller: This is due to the inverse square law. The light from the object spreads out over a larger area as it travels further, making the object appear dimmer and smaller.
* Dimmer: As the object moves further away, the intensity of its light decreases. This is because the light is spread out over a larger area.
* Redder: This is due to a phenomenon called redshift. As light travels through space, it stretches out, causing the wavelengths to shift towards the red end of the spectrum. This effect is more pronounced for objects that are moving away from us at high speeds.
It's important to note that the perceived size and brightness of an object can also be affected by factors like the object's intrinsic luminosity and the presence of intervening dust and gas.
