Heliocentric astronomy is a technology lecture and an article. Portions of it have been included in astronomy and in lofting technology.

You are free to take this quiz based on heliocentric astronomy at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, and in the {{astronomy resources}} and principles of radiation astronomy templates.

This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

A suggestion is to have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!


Point added for a correct answer:   
Points for a wrong answer:
Ignore the questions' coefficients:

1. The Solar Oscillation Imager (SOI) onboard Ulysses provides high precision solar images 1024x1024 of

velocity, line intensity, continuum intensity, longitudinal magnetic field and limb position.

2. Complete the text:

The Charge, Element, and Isotope Analysis System (CELIAS) aboard continuously samples the and energetic ions of solar, interplanetary and origin, as they sweep past SOHO.

3. Which of the following is not a characteristic of the Solar Wind Anisotropies (SWAN) instrument aboard SOHO?

only remote sensing instrument on SOHO
measuring the interaction between the solar wind and hydrogen gas
measuring hydrogen
watches the rest of the sky
looks at the Sun

4. Which of the following were performed by Ulysses?

passed the south solar pole
reached Jupiter for its "gravitational slingshot"
crossed the ecliptic equator
studied and monitored solar flares
put its cosmic gamma-ray burst detector into 'inactive' mode until it returned inside the orbit of Mars
detected and localized cosmic gamma-ray bursts
in-situ detection of Jovian aurorae

5. True or False, The Saturn V put SOHO into Earth orbit.


6. Yes or No, The Neutron Monitor aboard Ulysses was used to measure cosmic rays as well as neutrons.


7. Complete the text:

Match up the item letter with each of the possibilities below:
Balloons - A
Sounding rockets - B
Aircraft assisted launches - C
Orbital rocketry - D
Shuttle payload - E
Heliocentric rocketry - F
Exploratory rocketry - G
Lunar rover - H
Ranger 5
microcalorimeter arrays .

8. Yes or No, The Energetic and Relativistic Nuclei and Electron experiment (ERNE) aboard SOHO measures high-energy particles originating from the Sun and the Milky Way.


9. True or False, Heliocentric astronomy is astronomy performed from an approximately Sun-centered orbit.


10. Yes or No, The Variability of Solar Irradiance and Gravity Oscillations (VIRGO) on board SOHO characterizes solar intensity oscillations and measures the total solar irradiance (known as the ‘solar constant’) to quantify its variability over periods of days to the duration of the mission.
