If by parallel you mean that the axis points in the same direction throughout the year, the answer is yes.
Earth's eccentricity Eccentricity is defined as the difference in shape between an ellipse and a perfect circle. In a similar fashion to Earth's obliquity, the more uniform Earth's orbit is (more like a perfect circle), the less difference there is in climate change throughout the year.
the length of earths year is 365 days, tho its not really hahaha
how does earths distance from the sun change throughout the year
Assume your in the northern hemisphereThe earths rotational axis remains parallel throughout the year, winter is when the top of the axis is at full tilt away from the sun, summer is full tilt towards( half a year later)
Because the earths magnetic poles move around from year to year, and even day to day.

The year.
A year.
The earths rotational axis is tipped 23.5 degrees from vertical The earths rotational axis remains parallel throughout its orbit of the sun, so at one point in the yearly orbit the top half of the axis is at maximum tilt away from the sun, this is the winter solstice / shortest day (northern hemisphere) and summer solstice / longest day (southern hemisphere) Half a year later the positions are reversed as the axis remains parallel leaving the top of the axis tilting in.
takes longer to orbit the sun
Its the orientation of the earths rotational axis that defines the equinox, the axis remains parallel throughout the orbit of the sun, and when its side on to the sun (spring and autumn), thats the equinox (equal length of day and night).
Roughly 365.23 days. (rounded)
