Assuming this would have been taken in May and January, we have some simple trig to do.
1 second is 1/3600th of a degree, so 1/1200th of a degree is the parallax. We will need to use the diameter of the Earth's orbit, which is about 300 million kilometers. If we draw this, we see that we have an icoseles triangle. We bisect the top angle, which bisects the bottom side. We have two right triangles now, and we can use the sine of 1/2400 of a degree, which is 150,000,000/the distance. We divide this number by 150,000,000, getting 1/distance = 4.848 times 10^-14. We do this answer to the -1 to get an answer for distance, or 2.06*10^13 km, which is equal to 68,754,935 light years. This is for a perfect 3 seconds, so there is obviously a margin of error. However, I am thirteen years old and have never done this before, so it may be wrong. When stuck with a problem like this, my suggestion is to draw a picture.

What else can I help you with?
Is a star with no measurable parallax is very close to Earth.?
No, if you can measure no parallax, the star is far away - further than a certain distance.
Why would astronomers measure the parallax angle of a planet or star?
Astronomers measure the parallax angle of a planet or star to determine its distance from Earth. By observing the apparent shift in position of the object against the background stars as the Earth orbits the Sun, astronomers can calculate the angle and use it to estimate the object's distance.
If you determinee that a certain star displayed a large parallax what couls you say about its distance?
If a certain star displayed a large parallax, i would say its distance is not wide.
The measurement of the slight back-and-forth shifting in a nearby star's position due to the orbital motion of Earth is called?
The measurement of the slight back-and-forth shifting in a nearby star's position due to the orbital motion of Earth is called stellar parallax. This effect is used in astronomy to calculate the distance to stars and other celestial objects.
What is a stars parallax?
The parallax refers to the apparent change in the star's position, due to Earth's movement around the Sun. This parallax can be used to measure the distance to nearby stars (the closer the star, the larger will its parallax be).
If a star has a parallax of 0.20 arc seconds what is the distance to that star?
I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.
Is parallax a star?
The parallax refers to the apparent change in the star's position, due to Earth's movement around the Sun. This parallax can be used to measure the distance to nearby stars (the closer the star, the larger will its parallax be).
What does a big parralax say about a stars distance?
The larger a star's parallax, the closer the star is to us.
Apparent movement of a star used to measure its distance from earth?
Parallax is the apparent movement of a star when viewed from different positions in Earth's orbit around the Sun. By measuring this shift in position, astronomers can calculate the distance to the star using trigonometry. The closer a star is to Earth, the greater its parallax angle and the more accurately its distance can be determined.
If a star's parallax angle is too small to measure what can you conclude about the star's distance from earth?
It means that the distance is greater than a certain amount - depending on how precisely you can measure the parallax.
What is a name for the apparent movement of a star used to measure its distance from earth?
parallax
What is the apparent movement of a star used to measure its distance from earth?
The apparent movement of a star used to measure its distance from Earth is called parallax. Astronomers observe how a star's position changes relative to more distant stars as Earth orbits the Sun, allowing them to calculate the star's distance based on the angle of this shift.
How is the distance to a star determined using the measure of parallax?
The distance to a star can be determined using the measure of parallax by observing the star from two different points in Earth's orbit around the Sun. By measuring the apparent shift in the star's position against more distant background stars, astronomers can calculate the star's distance based on the angle of the parallax.
If a star's parallax angle is too small to measure what can you conclude about the star's distance from the earth?
It means that the distance is greater than a certain amount - depending on how precisely you can measure the parallax.
The method used to figure out the distance from Earth to a star is the?
Parallax. See related question.
Is a star with no measurable parallax is very close to Earth.?
No, if you can measure no parallax, the star is far away - further than a certain distance.
What measures star distance from the Earth?
Stellar Parallax Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. Simply put, they measure a star's apparent movement against the background of more distant stars as Earth revolves around the sun.
