How big is a BB in centimeters?
How big is a BB in centimeters?
The standard for a basketball in the National Basketball Association (NBA) is 29.5 inches (75 cm) in circumference and for the Women’s National Basketball Association (WNBA), a maximum circumference of 29 inches (74 cm).
How big is the sun’s surface area?
The sun has a radius of 695 x 106 m 4 giving a surface area of 6.07 x 1018 m2.
How far are the planets from the sun in CM?
| planet | distance from Sun relative |
|---|---|
| MERCURY | 30 cm |
| VENUS | 50 cm |
| EARTH | 75 cm |
| MARS | 1.5 meters |
Which is bigger the sun or the Earth?
The sun lies at the heart of the solar system, where it is by far the largest object. It holds 99.8% of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.
What is the biggest thing in the universe?
The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall. This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across!
How many Earths can fit in our sun?
1.3 million Earths
How many Earths can fit in the biggest star?
About 7.5477×1010 earths can fit in VY Canis Majoris.
Is the sun growing or shrinking?
The sun is growing. And shrinking, and growing again. Every 11 years, the sun’s radius oscillates by up to two kilometres, shrinking when its magnetic activity is high and expanding again as the activity decreases. We already know that the sun is not a static object.
How much fuel does the sun burn in 1 second?
The Sun consumes about 600 million tons of hydrogen per second.
What is wrong with the sun 2020?
Spaceweather.com reports that already there have been 100 days in 2020 when our Sun has displayed zero sunspots. That makes 2020 the second consecutive year of a record-setting low number of sunspots— which you can see (a complete absence of) here.
What year will the next solar minimum occur?
Solar Cycle 25 began in December 2019 and is expected to peak in 2025, according to the Solar Cycle 25 Prediction Panel, an international group of experts co-sponsored by NASA and NOAA. Specifically, December 2019 was the “solar minimum” or period of least solar activity in the 11-year solar cycle of the Sun.
Is the sun dying?
The hydrogen fuel at the core will finally be exhausted in five billion years when the Sun will be 67% more luminous than at present. This marks the end of the Sun’s main-sequence lifetime, and thereafter it will pass through the subgiant stage and evolve into a red giant.
How much longer will the earth last?
Indeed, it is generally thought that Earth’s biosphere will come to an end in the next 2 billion years due to the combination of overheating and CO2 scarcity for photosynthesis.
How old is space?
13.8 billion years
How long the sun will last?
Stars like our Sun burn for about nine or 10 billion years. So our Sun is about halfway through its life. But don’t worry. It still has about 5,000,000,000—five billion—years to go.
How long would life last without the sun?
With no sunlight, photosynthesis would stop, but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days, however, the temperatures would begin to drop, and any humans left on the planet’s surface would die soon after.
Is there life on the sun?
The Sun itself is not a good place for living things, with its hot, energetic mix of gases and plasma. But the Sun has made life on Earth possible, providing warmth as well as energy that organisms like plants use to form the basis of many food chains.
What happens when the sun dies?
After the Sun exhausts the hydrogen in its core, it will balloon into a red giant, consuming Venus and Mercury. Earth will become a scorched, lifeless rock — stripped of its atmosphere, its oceans boiled off. Astronomers aren’t sure exactly how close the Sun’s outer atmosphere will come to Earth.
Does dying hurt?
In most cases, when a patient is receiving the care and support of hospice, they will not experience pain during the dying process. Instead, their body will naturally begin to shut down. They will begin to have a decreased desire to eat and drink and will start to sleep more.
HOW LONG WAS A DAY 4 billion years ago?
About six hours. The days get longer because of the tidal influence of the moon. Eventually the length of our day will match the length of our annual trip around the sun. Based on astronomical data gathered over the last 400 years, the earth slows down about 2/1000s of a second per century.
How long would it take to die if the sun exploded?
A star needs to have a mass 10 times that of our sun in order for it to explode. If the sun were to explode it would take around 134 days for the shock wave to reach Earth. But the neutrinos and radiation travel at the speed of light and would reach us in 8 minutes and we would all die.
Do you die instantly in an explosion?
Anyone at or near the center of a nuclear explosion would be killed immediately by the fireball, searing radiation or the blast wave. Otherwise, what you should do depends on how far away you are from the explosion.
What will happen if the Earth stops rotating?
We know that the rotation of the Earth is gradually slowing down. Of course, if you suddenly stopped the Earth from spinning, most of our planet would rapidly become very inhospitable. Half of the planet would almost continuously face the heat of the Sun, while half would face the cold of space.
