How can we see the sun and stars from earth?
Sun and stars emits radiation in the form of visible light.
Nothing in space can stop light from reaching our eyes since it can travel through vacuum at a speed of 300,000 km/s. This includes light from the sun and stars.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- What caused Pangaea to break apart?
- Suppose we want to construct an accurate scale model of the Solar System and we use an orange (diameter 10 cm) to represent the Sun. How far away would we have to put Pluto?
- Do astronomers have another name for our moon?
- How far away is the center of our galaxy from the sun?
- Given the following information, does that mean the Earth will eventually change its axis of rotation to the vertical?
