- Solar sails are a proposed form of spacecraft propulsion using the radiation pressure from the sun.
- The Parker Solar Probe is a mission to study the outer corona of the Sun.
- During a solar minimum, the sun has fewer sunspots and less solar activity.
- Total Solar Irradiance (TSI) is a measure of the solar power over all wavelengths per unit area.
- The sunrise and sunset colors are due to the scattering of light caused by Earth’s atmosphere.
- Limbs of the Sun refer to the outer edge of the solar disk as seen from Earth.
- The sun’s equatorial rotation period is about 24 days, but it’s longer near the poles.
- Stellar nucleosynthesis in the sun produces heavier elements like carbon and oxygen.
- The Yohkoh satellite helped in understanding solar flares and coronal structures.

Sun Myths
![](https://1mfacts.com/wp-content/uploads/2023/12/Sun-Myths.webp)
Now that we’ve illuminated your mind with interesting facts about the sun, let’s shine a light on the myths and facts that often orbit around our star.
- The Sun is a Giant Ball of Fire
The sun is not actually on fire. It’s a massive sphere of plasma, primarily made of hydrogen and helium, undergoing nuclear fusion. This process converts hydrogen into helium in its core, releasing tremendous amounts of energy as light and heat. - The Sun is Yellow
It actually emits light that is white. The Earth’s atmosphere scatters blue light, making the sky appear blue and the sun yellow. From space, the sun looks more white than yellow. - Solar Flares Can Reach Earth
While solar flares are powerful bursts of radiation, they cannot physically reach Earth’s surface. However, when intense enough, they can disturb the atmosphere in the layer where GPS and communications signals travel. - The Sun is Unchanging and Constant
The sun is quite dynamic and changes over time. It has an 11-year solar cycle which includes periods of increased and decreased solar activity, affecting things like sunspots and solar flares. - Sunscreen is Only Needed on Sunny Days
UV rays from the sun can penetrate clouds, so it’s important to wear sunscreen even on cloudy days to protect your skin from harmful ultraviolet radiation.

Turn your face to the sun and the shadows fall behind you.
Maori proverb
This Maori proverb conveys a similar message to Whitman’s quote, encouraging a focus on the positive (the sun) so that the negative (shadows) is left behind.
Sun FAQ

As we transition from the inspiring world of sun quotes to the enlightening FAQs, remember to read each question carefully because the quiz is just after this section.
- Can sun poisoning make you sick?
Absolutely. Sun poisoning can definitely make you feel unwell. It’s a severe form of sunburn that not only damages your skin but can also cause symptoms like nausea, fever, chills, and dehydration. It’s really important to take sun exposure seriously and protect yourself with sunscreen, hats, and by seeking shade, especially during peak sun hours. - Where does the sun rise first in the world?
The first place to see the sunrise in the world is usually at the top of Mount Hikurangi in New Zealand. This spot is the first to greet the sun each day, given its location and elevation. However, this can change slightly throughout the year due to the Earth’s tilt and orbit. - Which sun rays cause cancer?
The sun emits ultraviolet (UV) rays that can be harmful to our skin. There are two main types of UV rays that reach the Earth’s surface – UVA and UVB. Both can cause skin cancer, but it’s mainly the UVB rays that are responsible for most skin cancers. They cause damage to the skin’s DNA, leading to mutations and eventually cancer if not protected against. - Why does the sun make you tired?
Spending time in the sun can be exhausting for a few reasons. Firstly, your body works hard to regulate its temperature in the heat, which can use up energy. Also, UV radiation can lead to dehydration, another energy drainer. Plus, being outdoors and active in the sunshine can naturally tire you out. - Is the sun a star or a planet?
It is definitely a star, and it’s our closest star at that! Unlike planets, which reflect light, stars like the sun produce their own light through nuclear fusion in their cores. This process converts hydrogen into helium, releasing a tremendous amount of energy in the form of light and heat, which is what we experience here on Earth.
