It took me long to post this because my computer was fixing a serious problem.

Well, btw, this is the problem.

**In Exercises 1-4, use the table shown which gives ****the apparent magnitude of several stars.**

A star's brightness as it appears to a person on Earth is measured on Earth is measured by its *apparent magnitude.* The lesser the apparent magnitude, the brighter the star.

Star | Apparent Magnitude |

Canopus | -0.7 |

Procyon | 0.4 |

Pollux | 1.1 |

Altair | 0.8 |

Spica | 1.0 |

Regulus | 1.4 |

Sirius | -1.5 |

Deneb | 1.3 |

Question 1) Which stars have an apparent magnitude that is less than the apparent magnitude of Altair?

Question 2) Which stars have an apparent magnitude that is greater than the apparent magnitude of Procyon?

Question 3) Which star has the least apparent magnitude and so looks the brightest?

Question 3) Which star has the greatest magnitude and so looks the dimmest?

Please help me. Thanks.

Question 1) Which stars have an apparent magnitude that is less than the apparent magnitude of Altair?

Look for all the starts that have apparent magnitudes that are **LESS** than 0.8...

**These would be Canopus, Sirius, & Procyon.**

Question 2) Which stars have an apparent magnitude that is greater than the apparent magnitude of Procyon?

Look for all the starts that have apparent magnitudes that are **GREATER** than 0.4...

**These would be Pollux, Altair, Spica, Regulus, & Deneb.**

Question 3) Which star has the least apparent magnitude and so looks the brightest?

**Sirius (-1.5).**

Question 4) Which star has the greatest magnitude and so looks the dimmest?

**Regulus (1.4).**

Thank you, AzizHusain. I needed to know that. I was told in the math book to do a line graph, but I didn't post it here.

Can you please do the line graph for me please?

Thanks.
