Stellar evolution

We may see thousands of stars in the dark sky. Our universe consists of billions of stars. Stars may appear tiny to us but they are huge balls of gasses. Sun is a star of average size. Some stars are even a thousand times larger than the sun. The stars do not exist forever they have a certain lifetime. The life span of the sun is about 10 billion years. The star undergoes various changes during its lifetime, this process is called stellar evolution. The structure of the sun-like star is shown below.

Red Shift

It is an astronomical phenomenon. In this phenomenon, increase in wavelength with corresponding decrease in photon energy and frequency of radiation of light. It is the displacement of spectrum of any kind of astronomical object to the longer wavelengths (red) side.

Question

### Understanding the Scale of Our Solar System

Our solar system is approximately 10 billion kilometers across. This diameter can also be expressed in different forms. Test your knowledge with the multiple-choice question below:

#### Question
Our solar system is approximately 10 billion km across. This diameter can be also be expressed as:

- **A.** \(10 \times 10^9\) km
- **B.** \(10^{10}\) km
- **C.** \(10^{13}\) m
- **D.** All of the above.
- **E.** Both a and b are correct

#### Explanation:

- **Option A:** \(10 \times 10^9\) km is an accurate way to express 10 billion kilometers because \(10^9\) is a billion.
- **Option B:** \(10^{10}\) km is incorrect as it represents a larger magnitude, 10 billion would simply be \(10^{10}\) not \(10^{10}\).
- **Option C:** \(10^{13}\) meters is correct since converting kilometers to meters involves multiplying by \(10^3\) (as 1 km = 1000 meters or \(10^3\) meters), so \(10^{10} \, \text{km} \times 10^3 = 10^{13} \, \text{m}\).
- **Option D:** All of the above would imply all options are correct but since B is incorrect, this option cannot be correct.
- **Option E:** This option suggests that both A and B are correct but since B is incorrect, this cannot be correct either.

#### Correct Answer:
**A. \(10 \times 10^9\) km** and **C. \(10^{13}\) m**

It is important to have an idea about the distances between and relative sizes of celestial objects in the solar system. In Part 1 we will pretend to shrink the solar system until its center piece, the Sun, is 67.3 cm in diameter. This will represent the Sun which is 1,390,000 km in diameter. The scale of our model is thus: 67.3 cm = 4.84 x 10-5 cm km Scale 1, 390, 000 km To find the size or distance between objects in centimeters for the model, simply multiply the actual size or distance in kilometers by the scale factor above. 1. Fill in following table: Quantity Actual Distance (km) Model Distance (cm) Diameter of Sun 1,390,000 Diameter of Earth 12,760 Diameter of Moon 3,480 Distance Between Earth and Sun 1.5 x 108 Distance Between Earth and Moon 384,000 Distance to Proxima Centauri 3.97 x 1013
1- MODIS is an Earth Observation sensor onboard TERRA spacecraft flying in a near-polar circular orbit with an orbital period of 98.8 minutes. The width of the swath imaged by MODIS is 2330 km. A- How many orbits does TERRA trace in one day? B- Assuming that the Earth rotates around its polar axis at a rate of 0.2618 rd/hr and that the equatorial radius is 6378 km, do two consecutive swaths of MODIS overlap at the equator?

Do two consecutive swaths of MODIS overlap at latitude 35 deg? 2- An aerostationary orbit for Mars is equivalent to a geostationary orbit for Earth. It is designed to enable a satellite in that orbit to image always the same surface of Mars.

You land on a strange spherical planet X. As a curious physicist, you set out to make the following measurements: (1) you observe that planet X has no appreciable atmosphere, (2) you measure that if you throw a 0.25 kg stone vertically upwards with launch speed 10 m/s, it comes back to ground in 8 sec, and (3) you measure the equatorial circumference to be 250,000 km. What is the mass of planet X? [Hint: The value of g on the planet surface is related to its mass M and radius R by the formula g = GM/R2.] a) 9*1025 kg b) 2.3*1027 kg c) 6.9*1026 kg If you take your spaceship to a 10,000 km altitude circular orbit around planet X, what would be the orbital period of the spaceship?

Read this main idea: The sun is the center of our solar system. Choose three details that go with the main idea. The sun's gravity holds the planets in place. It provides them with heat and light. The largest stars, called supergiants, are 1,500 times bigger than our sun. It takes Earth 365 days to orbit the sun. Jupiter takes 12 years! Our sun is not the largest or hottest star. It is a medium sized yellow star. Radio telescopes use radio waves to show stars in great detail. Astronomers long ago and today use star charts to map star locations. All of the planets in our solar system revolve around one star-our sun. Stars can be blue, white, yellow, or red. Blue stars are the hottest. A reflector telescope bounces star light through mirrors.
